What are LA-URs?
LA-UR stands for Los Alamos Unlimited Release, and LA-UR numbers are assigned by S-7, the Classification Group. Lab reports, the products of LANL research, are primarily published either as LA's (Los Alamos series reports) or as LA-URs. Many LA-URs are later published in books, conference proceedings or journals, but for others the LA-UR is the only "publication" of the research, cited by the LA-UR report number, and often difficult to find. LA-URs can range from a one-paragraph abstract to a 1000-page report. LANL staff may see S-7's LA-UR page for more information.

What LA-URs does the Library have?
The Library has many LAURs, but not all. S-7 sends us LA-URs in paper form, and we keep all LA-URs that are appropriate for addition to the collection (this excludes such items as abstracts, viewgraphs, and posters). Electronic format is acquired when possible — we depend on authors to provide copies (see below).

How do I find an LA-UR?
LA-URs can be searched in the Library Catalog, which has links to electronic copies when available. They can also be searched in the Los Alamos Authors Database, which is maintained by S-7 (667-5013).

Why do I get emails from the Research Library requesting my LA-UR's?
The Research Library sends out requests for LA-UR's to LANL authors on a monthly basis. Many of these requests are sent in order for the Laboratory to be in compliance with DOE Order 241.1. The Research Library, in coordination with the Classification Office (S-7) and Jacqueline M. Stack, the Scientific and Technical Information Officer for the Laboratory, has assumed the role of dissemination of LA-UR documents to the DOE's Office of Scientific and Technical Information (OSTI). S-7 makes the determination of which reports need to be sent to OSTI based upon requirements in the Order and accompanying guide. They then send the announcement to OSTI and notify the Research Library. The Research Library then sends out the request to the author for the report. OSTI will not accept paper copies of reports which is why we ask that you send us an electronic copy.

Sending your reports to the library not only helps the Laboratory be in compliance but also increases the visibility of your work. By having the reports available through the Library and through DOE Information Bridge (OSTI's point of dissemination), your work is easily accessible throughout the government research community at centralized locations.

The Research Library staff requests other reports that have been determined to be of value to researchers based upon the titles and format. These are generally items that have technical information that is not published elsewhere. We will also accept LA-UR's that authors send to us that they believe should be available to a wider audience.

We thank all staff members who have cooperated with the Research Library and Laboratory in their efforts to comply with the DOE Order and those who send us other reports to make available through the Research Library's web site.
