The Catalogue of Copyright Entries was the paper version of the registration and renewal records for the U.S. Copyright Office.  The Internet Archive digitized the U.S. Copyright Office's copy of the 660 volumes.  But not reliable database existed to search the records.  We have spent a year creating a searchable database that allows users to search all of the records, seeing both the original records and a list of records.  The tool is designed for experts wanting an efficient way to search the CCE records.  We also provide a link to the current records for convenience.
