The ALA Office for Information Technology Policy has released the Fair Use Evaluator and the Exceptions for Instructors eTool.
Here's an excerpt from the announcement:
The Fair Use Evaluator is an online tool that can help users understand how to determine if the use of a protected work is a "fair use." It helps users collect, organize, and document the information they may need to support a fair use claim, and provides a time-stamped PDF document for the users' records. . . .
The Exceptions for Instructors eTool guides users through the educational exceptions in U.S. copyright law, helping to explain and clarify rights and responsibilities for the performance and display of copyrighted content in traditional, distance and blended educational models.
