Join the community of research libraries in celebrating Fair Use Week from February 23-27! [1] Fair use is a limitation on a copyright holder’s exclusive rights providing that others may use the creator’s work without seeking permission. Determining fair use is guided by a 4-factor test. Yale Library has created a guide for information [2] about fair use and Yale’s Office of General Counsel, a fair use analysis tool [3] and copyright web site [4]. Read about fair use now and find out how this doctrine can help you with your research and studies!
