The U.S. Government Printing Office (GPO) is pleased to announce a ninety-day pilot that increases the z39.50 per session limit to 10,000 for download and retrieval of records from the Catalog of U.S. Government Publications (CGP), effective October 1, 2009. The existing z39.50 password will remain in place for the duration of the pilot.

The pilot is an incremental step in increasing access to bibliographic records in the CGP via z39.50, raising the per session limit for depository libraries. For the length of the pilot, GPO staff will closely monitor the effect of the ten-fold limit increase on the Integrated Library Service (ILS) servers. Although this is not anticipated, the pilot can be ended at any time should the ILS servers show extreme adverse effects from the increase in activity.
