1. Where do I go to copyright my book or manuscript?

Official U.S. Copyright Registration

In the United States, books and manuscripts are registered through the U.S. Copyright Office, which is part of the Library of Congress. The official online registration system is the Electronic Copyright Office, often referred to as “Eco”. Books, manuscripts, poetry, fiction, nonfiction, memoirs, devotionals, Bible studies, articles, curriculum, and similar written works generally fall under the Literary Works category. Authors can begin here:

Registering a Work FAQ
https://www.copyright.gov/help/faq/faq-register.html

Why Registration Matters

Many authors hear that their work is “automatically copyrighted” once it is written down. While copyright protection generally begins when an original work is fixed in a tangible form, that statement can be misleading for new authors if it causes them to believe they have done everything necessary to protect the work. Writing a manuscript does not stop someone from stealing, copying, uploading, publishing, distributing, imitating, or misusing the work. It also does not automatically give the author the strongest practical position if the author later needs to enforce their rights. For U.S. works, registration or refusal of registration is generally required before filing a copyright infringement lawsuit in federal court.

17 U.S.C. § 411 — Registration and Civil Infringement Actions
https://www.law.cornell.edu/uscode/text/17/411

Fourth Estate Public Benefit Corp. v. Wall-Street.com, LLC, 586 U.S. 296 (2019)
https://supreme.justia.com/cases/federal/us/586/17-571/

In Fourth Estate, the U.S. Supreme Court held that a copyright claimant may generally file an infringement lawsuit after the Copyright Office has acted on the registration application, not merely after the application has been submitted.

Registration and Statutory Damages

Registration timing can also affect whether statutory damages and attorney’s fees may be available.

17 U.S.C. § 412 — Registration as Prerequisite to Certain Remedies

https://www.law.cornell.edu/uscode/text/17/412

2. Is my book protected when I write it down?

The Legal Rule

Under U.S. law, copyright protection generally begins when an original work is fixed in a tangible medium of expression.

17 U.S.C. § 102 — Subject Matter of Copyright
https://www.law.cornell.edu/uscode/text/17/102

The statute says copyright protection exists in “original works of authorship fixed in any tangible medium of expression.” This means a manuscript may generally receive copyright protection when it is written, typed, saved, printed, recorded, or otherwise fixed in a form that can be perceived, reproduced, or communicated.

The Practical Reality for Authors

This does not mean an author should skip registration. Writing the manuscript may begin copyright protection, but it does not automatically create the strongest enforceable record if someone later copies, steals, uploads, republishes, distributes, sells, adapts, or misuses the work.

A clear way to explain it: Writing it down may begin copyright protection.

Registering it helps establish the official public record. For a serious book project, especially one being sold commercially or distributed through Amazon, IngramSpark, bookstores, churches, conferences, ministries, organizations, speaking events, or online platforms, registration through the U.S. Copyright Office should be strongly considered.

3. What does copyright protect?

Copyright Protects Original Expression

Copyright protects original creative expression. It does not protect every idea, topic, theme, title, fact, system, method, principle, or concept inside a book.

U.S. Copyright Office FAQ — What Does Copyright Protect? https://www.copyright.gov/help/faq/faq-protect.html

Copyright may protect:

• Original manuscript text.
• Original poems.
• Original devotionals.
• Original fiction scenes.
• Original illustrations.
• Original photographs.
• Original charts and graphics.
• Original workbook questions.
• Original study guides.
• Original curriculum.
• Original commentary.
• Original explanations.
• Original selection, coordination, and arrangement in some cases.

What Copyright Usually Does Not Protect

Copyright generally does not protect:

• Ideas.
• Facts.
• Book titles by themselves.
• Short phrases by themselves.
• General themes.
• Historical events.
• Methods.
• Systems.
• Common expressions.
• Public domain material.
• Basic concepts.
• General topics.

For example, many authors may write books on marriage, leadership, prayer, grief, trauma, addiction recovery, business, theology, mental health, parenting, or personal development. Copyright does not give one author ownership of the subject itself. It protects that author’s specific expression of the subject.

4. What rights does a copyright owner have?

Exclusive Rights Under U.S. Law

Copyright owners have specific exclusive rights under federal law. 17 U.S.C. § 106 — Exclusive Rights in Copyrighted Works https://www.law.cornell.edu/uscode/text/17/106

The copyright owner generally has the exclusive right to:

• Reproduce the work.
• Prepare derivative works based on the work.
• Distribute copies of the work.
• Publicly perform certain works.
• Publicly display certain works.
• Perform sound recordings publicly by digital audio transmission.

What This Means for Authors

For book authors, these rights may connect to:

• Print rights.
• eBook rights.
• Audiobook rights.
• Translation rights.
• Foreign rights.
• Film rights.
• Television rights.
• Streaming rights.
• Stage rights.
• Merchandising rights.
• Curriculum rights.
• Workbook rights.
• Podcast adaptation rights.
• Excerpt rights.
• Reprint rights.
• Licensing rights.

Publishing rights are not one single right. They are a bundle of rights. Authors should understand what they own, what they are licensing, what they are selling, what they are granting, and what they are keeping.

5. What is copyright infringement?

Definition

Copyright infringement occurs when someone violates one of the copyright owner’s exclusive rights without permission and without a valid legal defense.

17 U.S.C. § 501 — Copyright Infringement: https://www.law.cornell.edu/uscode/text/17/501

In plain language, infringement may occur when an author uses protected material created by someone else without permission in a way the law does not allow.

Common Examples of Copyright Infringement

Possible examples include:

• Copying paragraphs from another book into your book.
• Using song lyrics without permission.
• Reprinting poems without permission.
• Using copyrighted photographs from the internet.
• Copying charts, diagrams, graphics, or illustrations.
• Using another author’s workbook exercises.
• Reproducing study Bible notes or devotional content.
• Using copyrighted curriculum without permission.
• Copying online articles.
• Using copyrighted artwork, maps, or images.
• Creating an unauthorized sequel or adaptation based on someone else’s protected work.
• Uploading, selling, or distributing unauthorized copies of another person’s book.

Giving Credit Is Not the Same as Permission

Giving credit does not automatically make the use legal. A citation may identify the source, but it does not grant permission. “Used by credit” is not the same as “used by permission.” Duke University Libraries explains the distinction clearly: citation may address plagiarism, but citation does not automatically cure copyright infringement.

Duke University Libraries — Citation and Infringement: https://blogs.library.duke.edu/scholcomm/2007/11/30/citation-infringement/

6. What are the possible damages for copyright infringement?

Actual Damages, Profits, and Statutory Damages

Copyright remedies may include actual damages, infringer’s profits, statutory damages, injunctions, impounding or destruction of infringing copies, costs, and attorney’s fees, depending on the facts and timing of registration.

17 U.S.C. § 502 — Injunctions https://www.law.cornell.edu/uscode/text/17/502

17 U.S.C. § 503 — Impounding and Disposition of Infringing Articles https://www.law.cornell.edu/uscode/text/17/503

17 U.S.C. § 504 — Damages and Profits https://www.law.cornell.edu/uscode/text/17/504

17 U.S.C. § 505 — Costs and Attorney’s Fees https://www.law.cornell.edu/uscode/text/17/505

Statutory Damages

Under 17 U.S.C. § 504, statutory damages generally range from $750 to $30,000 per infringed work. If infringement is found to be willful, the court may increase statutory damages up to $150,000 per infringed work. If infringement is found to be innocent, damages may be reduced as low as $200 per infringed work.

17 U.S.C. § 504 https://www.law.cornell.edu/uscode/text/17/504

Why Registration Timing Matters

Under 17 U.S.C. § 412, statutory damages and attorney’s fees may not be available in certain situations if the work was not registered before infringement began or, for published works, within three months after first publication.

17 U.S.C. § 412 https://www.law.cornell.edu/uscode/text/17/412

This is one of the strongest practical reasons authors should take registration seriously.

7. What is Fair Use?

Definition

Fair Use is a legal doctrine that allows limited use of copyrighted material without permission in certain circumstances. Fair Use is part of U.S. copyright law.

17 U.S.C. § 107 — Fair Use: https://www.law.cornell.edu/uscode/text/17/107

U.S. Copyright Office Fair Use page: https://www.copyright.gov/fair-use/

Fair Use may apply to certain uses such as criticism, comment, news reporting, teaching, scholarship, or research. However, Fair Use is not automatic. Courts evaluate Fair Use by looking at four factors.

The Four Fair Use Factors

The four factors are:

• The purpose and character of the use, including whether the use is commercial or nonprofit educational and whether the use is transformative.
• The nature of the copyrighted work, including whether the original work is factual or highly creative.
• The amount and substantiality of the portion used, including both how much was used and whether the portion used was the most important part of the work.
• The effect of the use upon the potential market for or value of the copyrighted work.

No Automatic Word Count Rule

There is no automatic word count, percentage, page count, line count, or “10 percent rule” that guarantees Fair Use.

U.S. Copyright Office Fair Use FAQ: https://www.copyright.gov/help/faq/faq-fairuse.html

8. Is my book considered commercial use?

Commercial Use in Publishing

If your book is being sold, used to build your platform, connected to paid speaking, tied to your business, sold through Amazon, IngramSpark, bookstores, churches, conferences, ministries, courses, coaching, consulting, events, or organizations, it is safest to treat the book as a commercial project.

Commercial use does not automatically defeat Fair Use, but it matters. Under the first Fair Use factor, courts consider the purpose and character of the use, including whether the use is commercial or nonprofit educational.

17 U.S.C. § 107: https://www.law.cornell.edu/uscode/text/17/107

U.S. Copyright Office Fair Use: https://www.copyright.gov/fair-use/

9. How much can I quote from another book without permission?

No Universal Safe Amount

There is no universal word-count rule. There is no automatic “10 percent rule.” There is no guaranteed safe number of words, pages, lines, musical notes, images, screenshots, or percentage of a work.

U.S. Copyright Office Fair Use FAQ: https://www.copyright.gov/help/faq/faq-fairuse.html

A short quote may be low risk in one context and risky in another. A small portion may still be legally important if it contains the “heart” of the work.

Key Case: Harper & Row v. Nation Enterprises

Harper & Row v. Nation Enterprises, 471 U.S. 539 (1985), is one of the most important Fair Use cases authors should understand. The Nation published excerpts from President Gerald Ford’s unpublished memoir. The Supreme Court ruled against Fair Use. The amount copied was not enormous compared to the full manuscript, but the Court emphasized the importance of what was taken and the effect on the market.

Harper & Row v. Nation Enterprises: https://www.oyez.org/cases/1984/83-1632

Supreme Court opinion: https://supreme.justia.com/cases/federal/us/471/539/

The lesson is simple: short does not always mean safe.

10. What should I do if I find something in my book that is not mine?

Stop and Identify the Material

If your manuscript contains material you did not create, stop and identify exactly what it is. Do not ignore it. Do not assume it is safe because you found it online, changed a few words, cited the source, or saw another author use something similar. The U.S. Copyright Office’s Circular 16A explains that if you intend to use a work you did not create, you should determine its copyright status, regardless of where you discovered it. Unless a limitation or exception applies, permission may be needed from the copyright owner.

Circular 16A: How to Obtain Permission: https://www.copyright.gov/circs/circ16a.pdf

Practical Steps

If your manuscript contains third-party material:

• Identify the exact material.
• Identify where it came from.
• Determine whether it is protected by copyright.
• Determine whether it is public domain, licensed, original, or owned by someone else.
• Determine whether Fair Use may apply.
• Determine whether written permission is needed.
• Replace the material if permission is denied, too expensive, or uncertain.
• Keep records of all permissions, licenses, emails, receipts, and terms.
• Have a qualified intellectual property attorney review high-risk uses.

Do not send questionable material into final editing, interior design, upload, printing, distribution, or marketing hoping nobody notices.

11. How do I get permission to use copyrighted material?

Permission Means a License

Permission usually means receiving a license from the copyright owner. Only the current copyright owner of the exact material being used can grant permission. The original publisher may not always be the current rights holder because rights can be transferred, assigned, sold, licensed, or reverted.

U.S. Copyright Office Circular 16A: https://www.copyright.gov/circs/circ16a.pdf

What to Include in a Permission Request

A proper permission request should usually include:

• Your name and contact information.
• Your book title.
• Your publisher or imprint, if applicable.
• The exact material you want to use.
• The original source.
• The author, editor, translator, artist, photographer, or creator.
• The copyright date.
• The number of words, lines, pages, images, or figures.
• How the material will be used.
• Whether the book will be sold.
• Estimated print quantity or distribution scope.
• Formats requested: print, eBook, audiobook, online, curriculum, workbook, course, etc.
• Territory requested: United States, North America, worldwide, etc.
• Language requested: English, all languages, translation, etc.
• Term requested: one-time use, life of edition, all future editions, etc.
• Whether the rights requested are nonexclusive.

Written Permission Matters

Always get permission in writing. Verbal permission is weak. A written license, formal agreement, or clear permission email is much stronger.

12. What is public domain, and can I use older works?

Definition

Public domain works are works that are no longer protected by copyright or were never protected by copyright. Public domain works may generally be used without permission, but authors still need to verify the specific work and edition.

U.S. Copyright Office Definitions: https://www.copyright.gov/help/faq-definitions.html

Copyright duration depends on several factors, including when the work was created, whether it was published, whether it was registered, whether it was renewed, and whether it was created by an individual author, multiple authors, anonymous author, pseudonymous author, or as a work made for hire.

Copyright Duration FAQ: https://www.copyright.gov/help/faq/faq-duration.html

For works created on or after January 1, 1978, the general rule is life of the author plus 70 years.

13. Can I use song lyrics, poems, Bible translations, or quotes?

High-Risk Material

Authors should be especially careful with song lyrics and poems. These are often short, highly creative works, and even a small portion may be legally significant. Song lyrics are commonly controlled by music publishers and licensing organizations. Permission is often required. Poems are also high risk because using even a small portion can represent a substantial part of the original work. Bible translations require careful attention. Some translations are public domain in the United States, while many modern Bible translations are copyrighted and have specific publisher usage guidelines.

Bible Translation Note

The King James Version is generally treated as public domain in the United States, but many modern Bible translations are not. If using a Bible translation, check the translation publisher’s official permission guidelines. Do not assume all Bible text is free to use in unlimited amounts.

Common High-Risk Categories

Authors should be especially careful with:

• Song lyrics.
• Poems.
• Modern Bible translations.
• Study Bible notes.
• Devotionals.
• Photographs.
• Illustrations.
• Charts.
• Maps.
• Screenshots.
• Online articles.
• Curriculum.
• Workbook questions.
• Sermons.
• Speeches.
• Social media posts.
• Film dialogue.
• Television dialogue.
• Music samples.
• Artwork.
• AI-generated content that may closely resemble existing works.
• Anything copied from another book.

14. What about AI-generated content and copyright?

Human Authorship Still Matters

Artificial intelligence has created new copyright questions for authors. The U.S. Copyright Office has stated that copyright protection requires human authorship. Material generated solely by AI may not receive copyright protection in the same way as human-authored work.

U.S. Copyright Office AI page: https://www.copyright.gov/ai/

Works Containing Material Generated by Artificial Intelligence: https://www.copyright.gov/ai/ai_policy_guidance.pdf

AI Training and Copyright

The U.S. Copyright Office also released a report addressing generative AI training and copyrighted works.

15. Is there a legal term for intentional copyright infringement?

Willful Copyright Infringement

Yes. The main legal term for intentional copyright infringement is willful infringement.

Willful infringement generally means the infringer knew their conduct was infringing, acted with reckless disregard for the copyright owner’s rights, or acted with willful blindness. In practical terms, this may include knowingly copying protected material, ignoring permission requirements, continuing to use material after being warned, removing copyright notices, or deliberately avoiding the truth about whether permission was needed.

17 U.S.C. § 504 — Remedies for Infringement: Damages and Profits: https://www.law.cornell.edu/uscode/text/17/504

Under 17 U.S.C. § 504(c)(2), if the copyright owner proves and the court finds that infringement was committed willfully, the court may increase statutory damages up to $150,000 per infringed work.

Court Understanding of Willfulness

The Ninth Circuit Model Civil Jury Instructions explain willful infringement as infringement where the defendant engaged in acts that infringed copyright and knew those acts infringed copyright, or acted with reckless disregard for, or willful blindness to, the copyright holder’s rights.

Ninth Circuit Model Civil Jury Instructions — Willful Infringement: https://www.ce9.uscourts.gov/jury-instructions/node/708

Practical Examples of Willful Infringement

Willful infringement may include:

• An author knowingly copies several pages from another book and places them into their manuscript.
• A writer uses song lyrics after being told permission is required.
• A publisher continues selling a book after receiving credible notice that the book contains unlicensed copyrighted material.
• A person removes copyright notices from an image, article, or document and uses the material as if it were their own.
• A company uses copyrighted content after its license expired.
• A person deliberately avoids checking ownership because they do not want to pay for permission.

Willful infringement is serious because the court may increase damages significantly.

16. Is there a legal term for unintentional copyright infringement?

Innocent Copyright Infringement

Yes. The main legal term for unintentional copyright infringement is innocent infringement.

Innocent infringement does not mean no infringement occurred. It means the person infringed but claims they were not aware and had no reason to believe their acts constituted copyright infringement.

17 U.S.C. § 504(c)(2): https://www.law.cornell.edu/uscode/text/17/504

Under this section, if the infringer proves and the court finds that the infringer was not aware and had no reason to believe that their acts constituted copyright infringement, the court may reduce statutory damages to as low as $200 per work.

Innocent Infringement Is Not a Free Pass

A person can infringe unintentionally and still be legally responsible. The difference is usually in the level of damages, not whether infringement occurred.

For example, an author may accidentally use a copyrighted photograph from the internet, believing it was free. That author may not have intended to infringe, but the copyright owner may still have a claim. The author’s lack of intent may reduce damages in some circumstances, but it does not automatically eliminate liability.

Practical Examples of Innocent Infringement

Innocent infringement may include:

• An author uses an image found online without realizing it was copyrighted.
• A writer quotes too much from another book believing citation was enough.
• A ministry or nonprofit uses copyrighted curriculum believing nonprofit use is automatically allowed.
• A self-published author uses a poem from the internet believing it was public domain.
• A designer uses a stock image without realizing the license did not allow book cover use.

The person may not have intended harm, but the use may still violate copyright law.

18. What is criminal copyright infringement?

Criminal Infringement Requires Willfulness

Criminal copyright infringement is different from ordinary civil infringement. Criminal infringement requires willful conduct and must meet additional statutory requirements.

17 U.S.C. § 506 — Criminal Offenses: https://www.law.cornell.edu/uscode/text/17/506

18 U.S.C. § 2319 — Criminal Infringement of Copyright: https://www.law.cornell.edu/uscode/text/18/2319

Under 17 U.S.C. § 506, criminal copyright infringement may apply when a person willfully infringes copyright and the infringement is committed:

• For purposes of commercial advantage or private financial gain.
• By reproducing or distributing copies during a 180-day period with a total retail value above statutory thresholds.
• By distributing a work being prepared for commercial distribution through a publicly accessible computer network, knowing or having reason to know it was intended for commercial distribution.

Department of Justice Explanation

The U.S. Department of Justice explains that criminal copyright infringement generally requires proof of four elements:

• A valid copyright.
• Infringement by the defendant.
• Willfulness.
• Commercial advantage or private financial gain.

U.S. Department of Justice — Criminal Copyright Infringement

19. What is direct copyright infringement?

Direct Infringement

Direct infringement occurs when a person or entity directly violates one of the copyright owner’s exclusive rights without permission and without a valid legal defense.

17 U.S.C. § 106 — Exclusive Rights: https://www.law.cornell.edu/uscode/text/17/106

In plain English, direct infringement may occur when someone directly copies, uploads, sells, prints, distributes, adapts, displays, or performs protected material without permission.

Examples

Direct infringement may include:

• Copying text from another book into your manuscript.
• Uploading another person’s eBook and distributing it.
• Using copyrighted photographs in a book.
• Printing and selling unauthorized copies.
• Turning another author’s book into a workbook without permission.
• Using song lyrics without permission.
• Copying another person’s illustrations into your book.

20. What is secondary copyright liability?

Liability for Someone Else’s Infringement

Secondary liability means a person or company may be liable for another person’s infringement under certain circumstances. The two major categories are:

• Contributory infringement.
• Vicarious infringement.

Contributory Infringement

Contributory infringement generally involves intentionally inducing, encouraging, or materially contributing to another person’s infringement.

MGM Studios, Inc. v. Grokster, Ltd., 545 U.S. 913 (2005): https://supreme.justia.com/cases/federal/us/545/913/

In Grokster, the Supreme Court held that one who distributes a device with the object of promoting its use to infringe copyright, shown by clear expression or other affirmative steps, may be liable for resulting infringement.

Cox Communications v. Sony Music Entertainment

In Cox Communications, Inc. v. Sony Music Entertainment, 607 U.S. ___ (2026), the U.S. Supreme Court addressed contributory copyright liability involving an internet service provider and user infringement.

Supreme Court opinion: https://www.supremecourt.gov/opinions/25pdf/24-171_bq7d.pdf

Oyez summary : https://www.oyez.org/cases/2025/24-171

The Court held that merely providing a general service, even with knowledge that some users may use it to infringe, is not enough for contributory liability. The copyright owner must show that the provider intended the service to be used for infringement. Intent can be shown by proving the provider induced infringement or provided a service tailored to infringement.

Vicarious Infringement

Vicarious infringement may occur when a person or company has the right and ability to supervise infringing activity and receives a direct financial benefit from that infringement. This can arise in business, platform, employer, venue, technology, distribution, or publishing-related settings, depending on the facts.

21. What is plagiarism?

Definition of Plagiarism

Plagiarism is using someone else’s words, ideas, structure, research, language, or creative expression and presenting it as your own without proper credit. Plagiarism is primarily an ethical, academic, professional, and reputational issue. It is not always the same thing as copyright infringement.

Purdue OWL — Plagiarism Overview: https://owl.purdue.edu/owl/avoiding_plagiarism/index.html

Purdue OWL — Plagiarism FAQ: https://owl.purdue.edu/owl/avoiding_plagiarism/plagiarism_faq.html

APA Style — Plagiarism: https://apastyle.apa.org/style-grammar-guidelines/citations/plagiarism

Plagiarism May Include

Plagiarism may include:

• Copying another author’s words without quotation marks or citation.
• Paraphrasing another person’s work too closely without attribution.
• Using another person’s ideas without credit.
• Taking research, outlines, structure, sermons, lessons, curriculum, or teaching points and presenting them as original.
• Using AI-generated or ghostwritten material while falsely presenting the work as entirely self-created, depending on context and representation.
• Reusing your own previously published material without disclosure in an academic or professional setting, often called self-plagiarism.

Plagiarism Is About Attribution

Plagiarism asks: Did you give proper credit?

Copyright infringement asks: Did you violate the copyright owner’s legal rights?

Those are related questions, but they are not the same question.

22. What is the difference between plagiarism and copyright infringement?

Plagiarism and Infringement Are Different

Plagiarism and copyright infringement can overlap, but they are not the same thing.

Plagiarism

Plagiarism is about attribution, honesty, and presenting work as your own. It may be unethical even when it is not illegal. It may involve ideas, facts, structure, research, wording, or language. It can occur even when the copied material is not protected by copyright. It is often handled by schools, publishers, employers, journals, professional associations, churches, media organizations, or platforms.

Copyright Infringement

Copyright infringement is a legal issue. It involves violating the copyright owner’s exclusive rights. It may occur even if you gave credit. It requires protected expression, not merely ideas or facts. It may result in legal claims, damages, injunctions, attorney’s fees, and other remedies.

Simple Examples

• If an author copies a public domain paragraph and pretends they wrote it, that may be plagiarism, but it may not be copyright infringement because the material is public domain.
• If an author uses a copyrighted poem with full credit but without permission, that may not be plagiarism because credit was given, but it may still be copyright infringement.
• If an author copies several pages from a modern book without credit and without permission, that may be both plagiarism and copyright infringement.
• If an author summarizes general facts from multiple sources and gives proper credit, that may be neither plagiarism nor infringement, depending on how it is done.

23. Is plagiarism illegal?

Usually Not by Itself in U.S. Copyright Law

In the United States, plagiarism by itself is not usually treated as a separate copyright-law cause of action. It is normally an ethical, academic, professional, contractual, or reputational offense. However, the same conduct that constitutes plagiarism may also create legal problems if it involves copyrighted expression, fraud, breach of contract, false advertising, misrepresentation, academic misconduct, employment misconduct, violation of publishing warranties, or violation of professional standards.

Important Case: Dastar v. Twentieth Century Fox

The U.S. Supreme Court addressed a related issue in Dastar Corp. v. Twentieth Century Fox Film Corp., 539 U.S. 23 (2003).

Dastar Corp. v. Twentieth Century Fox: https://supreme.justia.com/cases/federal/us/539/23/

Oyez summary: https://www.oyez.org/cases/2002/02-428

The Court held that the Lanham Act could not be used as a substitute for copyright law to create a broad attribution claim for communicative works. In simple terms, trademark law generally cannot be used to create a perpetual copyright-like right requiring attribution for public domain works. This case matters because it helps explain why plagiarism and copyright infringement are different. Failure to credit may be unethical or professionally serious, but copyright law is focused on protected legal rights, not every attribution issue.

24. Can someone infringe copyright without plagiarizing?

Yes

A person can infringe copyright even if they give credit.

Example: An author includes four lines from a modern song lyric, credits the songwriter, and lists the music publisher, but never obtains permission. That may still be copyright infringement because credit is not the same as permission.

Other examples:

• Using a copyrighted photo with the photographer’s name but no license.
• Reprinting a poem with full attribution but no permission.
• Including a chart from another book with a citation but no permission.
• Using copyrighted Bible study notes with credit but no license.

Credit may reduce confusion about authorship, but it does not automatically grant legal permission.

25. Can someone plagiarize without infringing copyright?

Yes

A person can plagiarize without infringing copyright if the copied material is not protected by copyright, if it is public domain, if it consists only of unprotected facts or ideas, or if the use is legally permitted but falsely presented as original.

Examples:

• Copying a public domain passage and pretending you wrote it.
• Using another person’s idea from a conversation without credit.
• Using facts from a source without proper attribution in an academic paper.
• Closely paraphrasing public domain material without credit.
• Reusing your own previously published material in a professional or academic context without disclosure.

This may not always be copyright infringement, but it can still damage credibility and violate academic, publishing, professional, or ethical standards.

26. Can copyright infringement be accidental?

Yes

Copyright infringement can be accidental. A person may not know the material was protected, may misunderstand Fair Use, may assume online material is free, may believe nonprofit use is safe, or may think giving credit is enough. However, accidental infringement may still be infringement. The distinction often affects damages. Innocent infringement may reduce damages, while willful infringement may increase damages.

17 U.S.C. § 504: https://www.law.cornell.edu/uscode/text/17/504

27. What is subconscious copying?

Copying Without Deliberate Intent

Subconscious copying is a concept most often discussed in music copyright cases, but the broader principle matters: a person may copy protected expression without deliberately intending to copy.

One widely known example is Bright Tunes Music Corp. v. Harrisongs Music, Ltd., involving George Harrison’s song “My Sweet Lord” and The Chiffons’ song “He’s So Fine.” The court found infringement even though the copying was described as subconscious rather than deliberately intentional.

Bright Tunes Music Corp. v. Harrisongs Music, Ltd., 420 F. Supp. 177 (S.D.N.Y. 1976)

Author Application

For authors, the safest practice is to avoid writing too closely from source material. Research should be digested, understood, and transformed into original expression. Notes should clearly separate direct quotes from summaries and original thoughts.

28. What is substantial similarity?

Copying Too Much Protected Expression

Substantial similarity is a copyright concept used to evaluate whether the accused work is too similar to the protected elements of the original work. Copyright does not protect ideas, facts, general themes, or basic concepts. It protects original expression. Therefore, courts often examine whether the accused work copied protected expression in a legally meaningful way.

Important Case: Feist Publications v. Rural Telephone Service

Feist Publications, Inc. v. Rural Telephone Service Co., 499 U.S. 340 (1991), is an important case on originality, facts, and copyright protection.

Feist Publications v. Rural Telephone: https://supreme.justia.com/cases/federal/us/499/340/

In Feist, the Supreme Court held that facts are not protected by copyright and rejected the “sweat of the brow” theory. Effort alone does not create copyright protection. Originality matters.

Author Application

Two books can cover the same topic. Two authors can teach the same general principle. Two pastors can preach from the same Scripture passage. Two business writers can address the same leadership concept. The legal concern arises when one person copies another person’s protected expression, structure, wording, illustrations, original arrangement, or creative presentation.

29. What is a derivative work?

Definition

A derivative work is a new work based upon one or more preexisting works.

17 U.S.C. § 101 — Definitions: https://www.law.cornell.edu/uscode/text/17/101

17 U.S.C. § 106 — Exclusive Rights: https://www.law.cornell.edu/uscode/text/17/106

The copyright owner has the exclusive right to prepare derivative works based on the original work.

Examples of Derivative Works

Derivative works may include:

• Translations.
• Adaptations.
• Movie versions.
• Stage versions.
• Audiobook adaptations in some contexts.
• Sequels based on protected characters or storylines.
• Workbooks based on another book.
• Curriculum based on another author’s book.
• Condensed versions.
• Illustrated versions.
• Revised editions using protected original content.
• Screenplays based on books.
• Unauthorized study guides using protected expression.

30. What is copyright piracy?

Definition

Piracy is a common term for unauthorized copying and distribution of protected works. It is often used in connection with music, film, software, eBooks, audiobooks, digital downloads, and online distribution.

Piracy may include:

• Uploading unauthorized copies of eBooks.
• Selling unauthorized PDFs.
• Sharing illegal audiobook files.
• Distributing bootleg copies.

31. What is the Copyright Claims Board?

Small Copyright Claims

The Copyright Claims Board, often called the CCB, is a tribunal within the U.S. Copyright Office designed to provide a streamlined alternative to federal court for certain smaller copyright disputes.

Copyright Claims Board: https://ccb.gov/

U.S. Copyright Office — Small Claims: https://www.copyright.gov/about/small-claims/

CCB FAQ: https://ccb.gov/faq/

The CCB handles certain copyright disputes involving claims up to $30,000. It is voluntary, and respondents have the right to opt out.

Why Authors Should Know About It

Federal copyright litigation can be expensive. The CCB may provide a more accessible option for some creators and authors with smaller claims. However, authors should still seek qualified legal advice before filing, responding, or opting out of a claim.

32. What other legal terms relate to stealing, copying, infringement, or plagiarism?

Important Legal and Publishing Terms

17 U.S.C. § 506(e): https://www.law.cornell.edu/uscode/text/17/506

33. What should an author do if they may have infringed or plagiarized?

Stop Before Publishing

If an author discovers questionable material in a manuscript, the author should stop before publishing, uploading, printing, distributing, selling, or marketing the book.

Practical Steps

The author should:

• Identify the material.
• Identify the original source.
• Determine whether the material is protected by copyright.
• Determine whether the material is public domain.
• Determine whether a license already exists.
• Determine whether Fair Use may apply.
• Determine whether permission is needed.
• Remove or replace the material if permission is uncertain.
• Keep written records of sources, licenses, permissions, and correspondence.
• Consult a qualified intellectual property attorney when the issue is significant.

If the Book Is Already Published

If the book is already published, the author should act quickly and carefully. Depending on the issue, steps may include:

• Pausing sales or distribution.
• Removing the content from future printings.
• Uploading corrected files.
• Contacting the rights holder.
• Seeking a retroactive license if appropriate.
• Consulting legal counsel.
• Documenting all corrective actions.
• Not admitting legal liability without legal advice.
• Not ignoring cease-and-desist letters, platform notices, or claims.

34. What are common copyright mistakes authors make?

Common Mistakes

Many copyright problems begin with good intentions and poor information. Authors often believe they are safe because they cited the source, found something online, used only a little, changed a few words, are writing a Christian or educational book, are not famous, or are self-publishing.

Common mistakes include:

• Assuming anything online is free.
• Assuming giving credit is the same as permission.
• Assuming nonprofit or ministry use is automatically Fair Use.
• Assuming educational use is automatically Fair Use.
• Assuming a short quote is always safe.
• Assuming song lyrics are safe if only one or two lines are used.
• Assuming all Bible translations are free to quote without limits.
• Assuming public domain applies to every edition of an old work.
• Assuming AI output is automatically copyright-safe.
• Assuming changing a few words avoids infringement.
• Assuming a publisher, editor, or designer will catch every issue at the last minute.
• Assuming a copyright notice alone is the same as federal registration.
• Assuming registration is unnecessary because the manuscript was written down.
• Assuming permission from one person is enough when multiple rights holders may exist.
• Assuming stock images, fonts, or design assets can be used in any commercial book without reading the license.

35. What landmark copyright and Fair Use cases should authors know?

Folsom v. Marsh, 1841

Folsom v. Marsh, 9 F. Cas. 342 (C.C.D. Mass. 1841), is one of the early foundational Fair Use cases in American copyright law. It involved copying from George Washington’s letters and helped shape early Fair Use analysis before Fair Use was formally codified in the Copyright Act.

Oyez summary: https://www.oyez.org/cases/2025/24-171

This case is important because the Court clarified that merely providing a general service, even with knowledge that some users may use the service to infringe, is not enough for contributory liability without the required intent.

Bright Tunes Music Corp. v. Harrisongs Music, 1976

Bright Tunes Music Corp. v. Harrisongs Music, Ltd., 420 F. Supp. 177 (S.D.N.Y. 1976), is widely discussed in connection with subconscious copying. It involved George Harrison’s “My Sweet Lord” and The Chiffons’ “He’s So Fine.”
