Primary Source materials - even those on the internet - may be protected by copyright. It is important to verify copyright before using materials in your classroom.

Copyright On Library of Congress Materials

Copyright law covers the reproduction of protected materials. This includes using them in presentations, printing them, or putting them on a website. When using materials from the Library of Congress website, you can avoid any copyright issues by making links to the resource.

There are two exceptions to copyright on materials from the LOC:
  • Items published before 1923.
  • Resources created by the federal government and its employees as part of their job.

When you need to reproduce a Primary Source that you believe is covered by copyright you may be able to do so under Fair Use.
  1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
  2. the nature of the copyrighted work;
  3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
  4. the effect of the use upon the potential market for or value of the copyrighted work.

Always check the Rights and Reproduction section of the resource.
