Fair use relies on four factors to determine if it Fair Use can be applied to the usage of material in relationship to photocopies, showing parts of a film, posting an article from a book or journal.
The four factors are:
1. Purpose: educational or commercial
2. Nature of the work: creative or fiction or factual or non-fiction
3. Quantity of the work used: the percentage in relationship to the entire work, a rule of thumb is less than 10 percent
4. Financial effect on the market
All factors are used together to determine if it is Fair Use. If you are using it for education, it is non-fiction, you use less then 10 percent, and there is very little effect on the market, then fair use applies.
