CPRS Pilot (1978-Present): This is a pilot database that uses a more powerful search engine than the Official Public Catalog and provides easy filtering capability. It also includes images and searchable metadata from an initial release of Card Catalog registration applications from the 19381945 period. Note that there may be a delay of a day or more in the results displayed in this system as compared to the Official Public Catalog.
Virtual Card Catalog (1870-1977): This database contains over 41.5 million scanned card images from the U.S. Copyright Card Catalog, which provides an index to registrations and other records from 1870 through 1977.

Catalog of Copyright Entries (1891-1978): This is a series of books that list all works registered and documents recorded by the Copyright Office from 1891 through 1978. The books are arranged by year and category, and include indexes by author, title, and subject.

You will still need to request copies of the actual records from the Copyright Office.
Early Copyright Records Collection (1790-1870): This database contains records of works registered under federal copyright laws from 1790 through 1870.
