It provides an index to copyright registrations and other public records pertaining to ownership of copyrighted works. The catalog enables users to identify original copyright registration records and other U.S. Copyright Office records from 1870 through 1977. The information in these records typically includes: author(s), title of work, copyright registration number, and effective date of registration. These records do not include the full registration records or copies of deposited works registered with the Copyright Office. The card catalog also contains entries for transfers of ownership, generally one card for each title, assignee, and assignor.
Over the decades, with changes in the rules of cataloging copyright registrations, the U.S. Copyright Office has organized these records into several chronological periods or indexes. The indexes available in this Proof of Concept are the latest sections of the card catalog, interfiled alphabetically, covering registrations from 1955 through December 31, 1977, the last day on which works were registered under the 1909 copyright law.
THE PURPOSE OF THE VIRTUAL CARD CATALOG
The Proof of Concept card catalog represents a small sample set of card records, displayed in JPEG images, from the U.S. Copyright Card Catalog collection. It is not a final version of the planned Virtual Card Catalog (VCC). The images are presented in a similar filing order as found in the physical card catalog and may contain filing errors and corrupt images. In addition, the enhanced browse capabilities are limited due to the use of raw OCR data. We are working to update and improve the overall functionality.
The purpose of this Proof of Concept is to provide the public with a glimpse of the digitized card catalog and to solicit feedback that will provide valuable information for the future digital transformation of the U.S. Copyright Office physical historical records.
