Watch: Artist, Writers, and their Copyright Holders
The WATCH File (Writers, Artists, and Their Copyright Holders) is a database containing primarily the names and addresses of copyright holders or contact persons for authors and artists whose archives are housed, in whole or in part, in libraries and archives in North America and the United Kingdom. The objective in making the database available is to provide information to scholars about whom to contact for permission to publish text and images that still enjoy copyright protection. WATCH is a joint project of the Harry Ransom Humanities Research Center at The University of Texas at Austin and the University of Reading Library, Reading, England.
