Fair use allows limited use of copyrighted material without permission for purposes like teaching, research, and scholarship. It’s decided by a four-factor test, not fixed rules. The TEACH Act covers online education. Common myths like “10% of a work is always fair use” are false. Fair use is legal; plagiarism is ethical—you can commit both simultaneously if you don’t cite sources. Use a fair use checklist to evaluate your specific case. When in doubt, seek permission or consult your institution’s copyright office.

What Is Fair Use? The Four-Factor Test

Fair use is a legal doctrine in U.S. copyright law (17 U.S.C. § 107) that allows limited use of copyrighted material without permission from the copyright holder for purposes such as:

  • Teaching (including classroom and online)
  • Research and scholarship
  • Criticism, comment, and news reporting

But fair use is not a bright-line rule. Courts decide fair use on a case-by-case basis using four statutory factors:

1. Purpose and Character of the Use

Favors fair use when:

  • Use is for teaching, research, scholarship, or non-profit education
  • Use is “transformative” — you add new meaning, context, or value (e.g., quoting to critique, analyzing in a literature review)

Weighs against fair use when:

  • Commercial use or profit motive
  • Use is merely superseding (replacing the original work)

Academic example: Quoting 200 words from a novel in your literary analysis to illustrate a point favors fair use. Scanning and posting an entire textbook chapter for students to read without permission does not.

2. Nature of the Copyrighted Work

Favors fair use when:

  • Using published, factual, or non-fiction works
  • Works that are already publicly available

Weighs against fair use when:

  • Using unpublished works
  • Highly creative works (fiction, art, music, poetry)

Academic example: Using data from a published scientific study in your research paper favors fair use. Using lyrics from a recently released song in your thesis weighs against fair use.

3. Amount and Substantiality of the Portion Used

Favors fair use when:

  • Only the amount necessary for your purpose is used
  • You use the “heart” of the work only when essential

Weighs against fair use when:

  • You use the entire work or a large portion
  • You use the most important or creative part even if it’s a small amount

Important: There is no set percentage (like 10% or 30%) that automatically qualifies as fair use. This is a common myth we’ll debunk below.

4. Effect on the Potential Market for the Work

Favors fair use when:

  • Your use does not substitute for the original work
  • There’s no existing market for licensing the material you’re using
  • Your use doesn’t harm the copyright owner’s ability to sell or license the work

Weighs against fair use when:

  • Your use could replace sales or licensing revenue
  • There’s an established market for the type of use you’re making (e.g., textbook excerpts that substitute for buying the book)

Fair Use vs. Plagiarism: Two Different Problems

One of the most common confusions in academia is the difference between fair use and plagiarism. They address different issues but can overlap.

Fair Use Plagiarism
Legal concept (copyright law) Ethical/disciplinary concept
About permission to use copyrighted material About attribution and claiming credit
Determined by the four-factor test Determined by whether sources are properly credited
Violations can lead to lawsuits and damages Violations can lead to academic penalties (failing grades, expulsion, retractions)

Key insight: You can have fair use and plagiarism at the same time. If you use a short quote under fair use but fail to cite it, you’re not infringing copyright, but you’re still plagiarizing.

Conversely: You can properly cite a source but still infringe copyright if your use exceeds fair use (e.g., copying an entire chapter with citation but no permission).

Bottom line: Always cite your sources, even if you believe your use qualifies as fair use. Proper citation protects you from plagiarism accusations; understanding fair use protects you from copyright infringement claims.

The TEACH Act: Fair Use for Online Education

For instructors teaching online or in hybrid formats, the TEACH Act of 2002 (Technology, Education, and Copyright Harmonization Act) expanded what’s allowed compared to traditional fair use.

What the TEACH Act Allows

The TEACH Act permits accredited, non-profit U.S. educational institutions to:

  • Perform and display copyrighted works in online courses
  • Make copies integral to the digital transmission (e.g., digitizing a film clip for a video lecture)
  • Use a broader range of materials than the face-to-face classroom exemption

TEACH Act Requirements (Must meet ALL)

  1. Institution must be:
    • Accredited, and
    • Non-profit (most colleges/universities qualify)
  2. Access must be restricted:
    • Only enrolled students may access the materials
    • Reasonable technological measures must prevent retention and further distribution
  3. Materials must be:
    • Lawfully made and acquired
    • Directly related to the teaching content (not supplemental entertainment)
    • Used for “digital transmissions” (online courses)
  4. Institutions must:
    • Provide copyright policy information to faculty, students, and staff
    • Not interfere with technological protection measures (DRM)

What the TEACH Act Does NOT Allow

  • Unlimited copying: You can’t post entire textbooks or course packs
  • Unrestricted access: Materials cannot be publicly available
  • Commercial use: Only for accredited, non-profit institutions
  • Performance of non-dramatic literary works: Separate rules apply

TEACH Act vs. Fair Use

The TEACH Act does not replace fair use. It’s an additional, specific exemption. If your use doesn’t qualify under TEACH, you may still argue fair use under the four-factor test.

Practical tip: When in doubt, use only the amount you need for the specific lesson, restrict access to enrolled students, and provide attribution. This approach generally favors both TEACH and fair use.

5 Common Fair Use Myths Debunked

Based on frequent questions from students and educators, here are the most persistent myths:

Myth 1: “Any educational use is automatically fair use.”

Reality: Educational purpose is one factor among four. Many educational uses qualify as fair use, but not all. Using an entire copyrighted work for convenience (e.g., scanning a whole novel for students) rarely qualifies, even in a classroom.

Myth 2: “Using 10% (or 30%) of a work is always fair use.”

Reality: There is no percentage rule in copyright law. The amount used must be evaluated in context. Sometimes using 1% of a work (the “heart” or most creative part) can weigh against fair use. Using 30% of a factual work might be fair if it’s necessary for your purpose.

Myth 3: “If I cite the source, it’s fair use.”

Reality: Citation prevents plagiarism, not copyright infringement. Fair use is about permission, not attribution. You can (and should) cite sources even when your use is fair use. But citing doesn’t automatically make an infringing use legal.

Myth 4: “If it’s on the internet, it’s free to use.”

Reality: Online availability does not mean the work is in the public domain or free to use. Most online content is protected by copyright. The same fair use analysis applies.

Myth 5: “Non-profit or personal use is always fair use.”

Reality: Non-profit status weighs in favor of fair use, but it’s not dispositive. A non-profit organization copying entire works for distribution could still infringe. The other three factors matter too.

Practical Fair Use Checklist for Students and Researchers

Use this decision framework when considering whether your proposed use likely qualifies as fair use. This is based on widely-used checklists from UChicago Library, Columbia University, and Cornell University.

Purpose & Character

  • [ ] Use is for teaching, research, scholarship, or criticism
  • [ ] Use is transformative (adds new meaning, analysis, or value)
  • [ ] Use is non-profit (not selling or monetizing)
  • [ ] Use is for a limited class or audience (not mass distribution)
  • Weighting: 3+ checks = favors fair use

Nature of the Work

  • [ ] Work is published (vs. unpublished)
  • [ ] Work is factual (non-fiction, data, facts) rather than creative (fiction, art, music)
  • [ ] Work is out of print or not commercially available
  • Weighting: 2+ checks = favors fair use

Amount Used

  • [ ] Only the amount necessary for your purpose is used
  • [ ] Portion used is not the “heart” or most valuable part
  • [ ] Amount used is small relative to the entire work (context-dependent)
  • [ ] You did not use the entire work if not necessary
  • Weighting: 3+ checks = favors fair use

Market Effect

  • [ ] Your use does not substitute for purchasing the original work
  • [ ] There’s no existing licensing mechanism for this type of use
  • [ ] Your use does not harm the copyright owner’s market
  • [ ] The work is not part of a commercial textbook/package where your use could reduce sales
  • Weighting: 3+ checks = favors fair use

Overall Assessment

  • If 10+ total checks: Strong fair use case
  • If 7-9 checks: Moderate fair use case (still reasonable, but document your analysis)
  • If 6 or fewer checks: Unlikely fair use — seek permission or use less material

Important: This checklist is a guidance tool, not legal advice. Courts are not bound by any checklist. Document your reasoning if you proceed under fair use.

When Should You Seek Permission?

Even if your use seems to favor fair use, consider seeking permission when:

  1. You’re using the “heart” of the work (the most memorable or creative part)
  2. Your use could substitute for market sales (e.g., copying an entire chapter from a textbook)
  3. The work is out of print but still under copyright (most works are protected for the author’s life + 70 years)
  4. You’re unsure about any factor — better safe than sued
  5. Your institution requires it — some universities have specific policies

How to seek permission:

  • Identify the copyright holder (author, publisher, or estate)
  • Send a written request specifying what you want to use, where, and for how long
  • Keep records of all correspondence
  • Be prepared to pay licensing fees if required

Recent Trends: AI Training and Fair Use

The legal landscape is evolving rapidly regarding artificial intelligence and copyright. In 2024–2025, courts have begun addressing whether using copyrighted works to train AI models qualifies as fair use.

Current Status

  • Courts are increasingly receptive to fair use arguments for AI training data in some contexts, especially for research and development.
  • Piracy and verbatim reproduction remain clearly infringing.
  • The outcome varies by jurisdiction and specific use case.

What This Means for Students and Researchers

  • Using AI tools (like ChatGPT) to help with research does not automatically infringe, but:
    • The AI’s output may contain copyrighted material from training data
    • You remain responsible for the content you submit
    • Cite AI use if your institution requires it
  • If you’re developing AI tools in academic research, understand that training on copyrighted works may require a fair use analysis or licensing

Bottom line: The law is unsettled. When using AI-generated content in academic work:

  • Verify facts and originality
  • Attribute AI assistance as required by your institution
  • Don’t assume AI output is free of copyright concerns

International Considerations

Fair use is primarily a U.S. doctrine. Other countries have similar but different exceptions:

  • United Kingdom, Canada, Australia: “Fair dealing” — more limited, specific enumerated purposes
  • European Union: Copyright exceptions vary by member state; some have education exceptions
  • Other countries: May have no equivalent; copyright laws can be stricter

If you’re studying or publishing internationally:

  • Check local laws before relying on fair use
  • When in doubt, seek permission or use materials clearly in the public domain

Practical Steps: Using Materials Responsibly

Here’s a quick workflow before using copyrighted material in your academic work:

  1. Ask: Is this necessary? Only use what you need.
  2. Check the source: Is it published? Creative or factual? In print or available?
  3. Apply the checklist: Complete the four-factor analysis above
  4. Document your reasoning: Keep notes on why you believe fair use applies
  5. Provide attribution: Always cite the source, regardless of fair use status
  6. When in doubt, ask: Consult your university’s copyright librarian or legal counsel
  7. Consider alternatives: Use public domain works, open-access materials, or Creative Commons-licensed content when possible
