Copyright Implementation Manual Part 5. Copying within the limits of the guidelines is fair use. Also, according to the guidelines, each copy must include a notice of copyright. In general, brevity limits poems to 250 words, complete prose works to 2,500 words, prose excerpts to 1,000 words, and illustrations to one per book or periodical.
Cumulative effect limits the number of copies that can be made.
These limits require that the copies made may only be used for one course and that no course can have over nine instances of multiple copying per term. In addition, only one complete work or two excerpts per author are allowed per term. Note that these limitations do not apply to current news. Also, copying must not be directed by a higher authority, repeated from term to term, or charged to students beyond the cost of photocopying. If you plan to use a work repeatedly, obtain permission.
