From the U.S. Copyright Office:
Today, the U.S. Copyright Office launched a new Copyright Public Records System (CPRS) pilot to the public. The new portal will provide access to the same copyright records for both registration and recordation data that exist in the Copyright Public Catalog but with enhanced search capabilities and improved interfaces for internal and external users. With these enhancements, users should have an easier time finding the exact records they need. The CPRS pilot is also the second Enterprise Copyright System module to launch. While the first module, the electronic recordation system pilot, was released to a limited external audience, the CPRS pilot is available to the entire public.
The public can access the new CPRS pilot at publicrecords.copyright.gov and provide feedback on their experience using the feedback link at the bottom of the page. For any questions or other comments, please email firstname.lastname@example.org.
The pilot is designed to run concurrently with the Copyright Public Catalog—available at cocatalog.loc.gov.
During the pilot, the Copyright Public Catalog will remain the official source of authoritative records. The CPRS pilot will continue to evolve after the public release. Developers and Copyright Office staff are working on including the ability to download and print search results and the ability for users to see their recent searches and records. While the current CPRS pilot contains records from 1978 through the present, the Office is considering migrating other public records to the CPRS.
