It is always important to analyze how you are going to use a particular work against the following four factors of fair use:
Purpose and Character: What is your purpose in using the materials? Are you going to use the material for monetary gain or for education or research purposes?
Nature: What is the characteristic nature of work - is it fact or fiction; has it been published or not?
Courts provide more protection to works of art and fiction than they do to factual or nonfiction works.
Amount: How much of the work are you going to use? Small amount or large? Is it the significant or central part of the work?
Amount is a very important factor to consider. Using large portions of a work is less likely to pass fair use muster. Always consider the size of a work in this context. Using 20 pages of a 500 page book is not a significant portion, whereas 20 pages out of a 50 page book would be.
Effect: How will your use of the work effect the author's or publisher's ability to sell the material? If your purpose is for research or education, your effect on the market value may be difficult to prove. However, if your purpose is commercial gain, then you are not following fair use.
