PLEASE NOTE: This Proof of Concept is
not the final version of the planned Virtual Card Catalog (VCC).
The purpose of the VCC Proof of Concept is to test if this
system can be used for online public access to the physical Copyright
Card Catalog. The images appear in roughly the same filing order as
the physical cards, but filing errors and corrupt images may cause
some images to be in the wrong place. Enhanced browse capabilities
are limited because data capture technology is not entirely accurate.
We are working to update and improve overall functionality. Your
feedback is essential to improving the system.
This Proof of Concept does not replace or supersede existing search
practices established by the U.S. Copyright Office. Any results
obtained during the course of your enhanced browse are not reliable
for legal matters. For information regarding searching copyright
records, please refer to Circular 22
"How to Investigate the Copyright Status of a Work." For information
regarding the removal of personal information from the Virtual Card
Catalog, please refer to the Circular 18
"Privacy: Copyright Public Records."
