This is a list of no-cost sources that list or index electronic texts, including journal articles or reports. At these sites you'll find electronic books, journal articles, scientific and technical reports, conference papers, fact sheets, news transcripts, preprints, theses and dissertations. Many provide the full texts online, or abstracts, while others merely list bibliographic citations.
Employees of the U.S. Department of the Interior are reminded they may also search for journal articles by using EBSCO Online, Gale In Context: Environmental Studies, JSTOR, or Science Direct. Most employees may search these databases at their desks, while others must come to the Library or contact a Reference Librarian for assistance.
And don't forget that the library staff has added many open access reports, books, and journals to the A-to-Z List.

Congressional Research Service Reports
Congressional Research Service reports can be the best way to quickly get up to speed on major political issues. CRS is Congress’ think tank, and its reports are relied upon by policymakers and others for accurate, timely and nonpartisan analysis of important policy issues.
Congressional Research Service Reports
Collected and made available by the University of North Texas Libraries.
The site claims to have more than 33,000 current and historical CRS reports.
In partnership with a Republican and Democratic member of Congress, EveryCRSReport.com includes reports available on Congress's internal website, more than 8,000 in all.
Library of Congress
The Consolidated Appropriations Act of 2018 directs the Library of Congress to make CRS reports publicly available online.
The result is a new public website for CRS reports based on the same search functionality that Congress uses – designed to be as user friendly as possible – that allows reports to be found by common keywords.
Moving forward, all new or updated reports will be added as they are made available to Congress. The Library is also working to make available the back catalog of previously published reports as expeditiously as possible.
