How many photocopies may be made of copyrighted material?

The number of photocopies that may be made of copyrighted material depends on the specific circumstances and the application of copyright law. In the United States, the "fair use" doctrine allows for limited use of copyrighted material without permission, but there is no strict numerical limit. Generally, making a single copy for personal use or for educational purposes may be acceptable, but making multiple copies or distributing them typically requires permission from the copyright holder. It’s always best to consult copyright guidelines or seek legal advice for specific situations.
