Quantity of copyrighted material is considered in the court when judging fair use. Even though under certain circumstances an entire copyrighted content has been seen as fair. Yet not all limited copyright material can be under fair use based on the content used, according to U.S. copyright office. There is no number that is acceptable under fair use and should be used according. The following cases include important factors with limited copyrighted material and have proven as fair use.
Religious Technology Center v. Pagliarina: Used three brief quotations and posted on internet.
The information was used for commentary and a only a small portion was used.
Authors Guild v. Google: Digital copies submitted of tens of millions of books.
Limited use of information and access of the books.
Wright v. Warner Books: Quoted six unpublished letters and ten unpublished journal entries.
The purpose was informational and less than 1% of letter and entries were used.
Copright Act uses four factors in order to see what can be used without permission which include:
1.The purpose and character of your use
2.The nature of the copyrighted work
3.The amount and substantiality of the portion taken, and
4.The effect of the use upon the potential market.
Even though every situation is different there may be a need for more than one factor and when in doubt should ask for permission.
