Holdings Overview

The PDR collection consists of a variety of agency documents, including NRC NUREG-series publications, Weekly Information Reports, transcripts of Commission meetings, existing and proposed regulations and amendments, material from NRC's licensing dockets, and correspondence on technical, legal, and policy matters. See Reference Materials and Document Holdings and Organization for details.

Older materials are maintained in microfiche and paper. More recent materials are available in electronic form. Users may have documents from the collection, with some exceptions, reproduced for a fee. See Copy Service and Fees for details.

Searches and Printouts of Electronic Holdings

To help users find documents, the PDR provides access to the online document system: the Agencywide Documents Access and Management System (ADAMS).

The ADAMS Publicly Available Records System (PARS) database contains bibliographic citations and full text of public records released since November 1, 1999, with the exception of certain large documents that may only be available in paper or CD-ROM. ADAMS can be accessed onsite, using the terminals in the PDR, or offsite using the instructions found on the ADAMS page at this Web site. ADAMS does not require a password.

The ADAMS Public Legacy Library (PLL) contains descriptive citations indexing the majority of documents placed in the PDR after October 1978 and selected documents for 1967 through 1978.

The librarians can perform searches on ADAMS PARS and/or PLL and generate printouts upon request. Printouts of limited size can be printed and held for pickup or mailed. Search results can also be downloaded and e-mailed as ASCII (plain text) files.

Access to Paper and Microfiche Holdings

The PDR provides access to a complete archive of NRC pre-ADAMS publicly available documents that are still retained as agency records in paper and/or microfiche and in some other formats in special cases.

Access to Electronic Holdings

The NRC sometimes makes its documents available on CD-ROM or DVD-ROM. The PDR has many of these discs in its collection. However, they can neither be copied nor read by the equipment in the PDR. Members of the public can request copies of the discs through the PDR copy service. See Copy Service and Fees.

Equipment Available to the Public

Members of the public may access the NRC Web site and ADAMS database from terminals in the PDR without charge. However, these terminals do not allow for the downloading of Web pages, NRC documents or other items to media such as USB drives or CD-ROMs.

Document Requests

Offsite users may order documents from the reference staff. A reference librarian will verify the citations and give the PDR copy service the order for the documents. See Copy Service and Fees.
