CGP Records with Updated PURLs
GPO has updated 191,129 PURLs in 170,501 CGP records. The records are posted on the CGP on GitHub repository. GitHub is a web-based computer source code sharing and publishing service; files are available in MARC-8 and UTF-8, and the records are split into four files. Some records do not contain OCLC numbers. A GitHub account is not required for downloading the records and viewing the descriptions of the record sets.
A small number of Federal depository libraries recently experienced issues with access to electronic resources within the Catalog of U.S. Government Publications (CGP). GPO identified the source, which is related to the adoption of a new protocol called Domain Name System Security Extensions (DNSSEC). Internet service or network providers that have adopted the DNSSEC will not resolve links whose websites are not configured for DNSSEC. This includes retired domains that are unable to validate and confirm what the security system is requiring.
Libraries can use the files to replace the current PURLs with the updated PURLs. For more information on how GPO updated the PURLs, please see the news alert, PURL Access Issues Update.
