'Fair Use' allows for using materials for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.
Important to note is the 'Rule of Four':
(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.
Two additional considerations when making copies for classroom use are brevity and spontaneity. General guidelines limit copying to not more than 10% of a book.The decision to use the work is so close in time to providing it to the class makes it unreasonable to expect a timely reply to a request for permission.
