From GPO’s Administrative Notes:
GPO is working with the library community on a national digitization plan with the goal of digitizing a complete legacy collection of tangible U.S. Government publications held in libraries participating in the Federal Depository Library Program (FDLP).
The objective is a digital collection available, in the public domain, for permanent public access through the FDLP. The legacy collection of what has been distributed since the beginning of the Federal Depository Library Program includes approximately 2.2 million print documents.
GPO conducted a survey of our depository partners to determine which tangible U.S. Government documents are most important to digitize and in which priority. Results of the Digitization Ranking Survey indicate the five most urgent titles, including the Congressional Record (Bound), the U.S. Congressional Serial Set, the Statistical Abstract of the U. S., the U.S. Statutes At Large and the Code of Federal Regulations.
