248 within that field. Moreover, the history of fair use litigation of all kinds shows that judges return again and again to two key analytical questions: These two questions effectively collapse the “four factors.” The first addresses the first two factors, and the second rephrases the third factor. Both key questions touch on the so-called “fourth factor,” whether the use will cause excessive economic harm to the copyright owner. If the answers to these two questions are “yes,” a court is likely to find a use fair—even if the work is used in its entirety. Because that is true, the risk of a challenge to such a use is dramatically reduced.
 * Did the use “transform” the material taken from the copyrighted work by using it for a broadly beneficial purpose different from that of the original, or did it just repeat the work for the same intent and value as the original?
 * Was the material taken appropriate in kind and amount, considering the nature of the copyrighted work and of the use?

Fair use ensures that copyright owners do not have a monopoly over transformative uses of their works. The converse is also true. When a use merely supplants a copyright owner’s core market rather than having a transformative purpose, it is unlikely to be fair. Thus, for example, a library clearly cannot acquire current books for its collection simply by photocopying or scanning published editions.

In cases decided since the early 1990s, the courts have made it clear that in order for a use to be considered “transformative,” it need not be one that modifies or literally revises copyrighted material. In fact, uses that repurpose or recontextualize copyrighted content in order to present it to a new audience for a new purpose can qualify as well. The courts also have taught that the more coherent an account the user can give of how and why the material was borrowed, the more likely the use is to be considered transformative.

A final consideration influencing judges’ decisions historically has been whether the user acted reasonably and in good faith in light of standards of accepted practice in his or her particular field. Among the eight other communities of practice that established codes of best practices
