Browse online to the Public Copyright Catalog.
Choose the criteria you want to use to find the copyright information. General searches, such as names, will yield several results. More specific information, such as the copyright number, will yield better results.
Search through the listings for the copyright you are looking for and click on its link.
Scroll down through the available information to 'Copyright Claimant' for the name of the person who owns the copyright. Some entries will also have a section called "Names." These are people who are important to the copyright for some reason, often former or future holders or representatives for the company or group that holds the copyright.
