If you make copies of any material, whether electronic or paper based, you need to keep in mind the concept of “fair use”. Copyright law allows for some flexibility, within reason, and depends on the interpretation of four factors:

  1. The purpose for which the copy is made.
  2. The nature of the work that is copyrighted.
  3. The portion of the work that is copied.
  4. The effect on the market for the original work.
