The US Department of Energy and Government Printing Office have combined to provide this resource, a searchable directory of "full text and bibliographic records of report literature produced by the DOE and DOE contractor research and development community." Reports are available since 1996 at this time and may be searched by three fields in the easy search and fourteen in the advanced search. Boolean AND/OR/NOT searching is available in the advanced search, and up to five fields can be connected this way (note that the Boolean connector choice is a drop down menu at the far right of the frame). Documents may be retrieved page by page or in their entirety (Adobe Acrobat [.pdf] page scans). One of the more useful features of the site is the ability to search within a document once documents are retrieved (bottom frame). Four page image viewers are available. Note that the legibility of publications varies by viewer and publication, and that the site is sometimes down form maintenance between 12:00 and 4:00 AM Eastern time. As the site grows, it will become a magnificent source of DOE sponsored research literature.
