The U.S. Government Printing Office (GPO) recently announced that they are expanding their eBook program to provide free public access to federal government eBooks through their online Catalog of U.S. Government Publications. Currently, the free eBook collection includes over 125 titles, but GPO plans to add more titles every month. Many of the books such as The Effectiveness of Drone Strikes in Counterinsurgency and Counterterrorism Campaigns, Making Sense of DNA Backlogs 2012: Myths vs. Reality, and NASA at 50: Interviews with NASA’s Senior Leadership may be of interest to scholars. Other titles such as In the Loop: A Reference Guide to American English Idioms and Baseball: The National Pastime in the National Archives are of more general interest.
To find eBooks, you can search the Catalog of U.S. Government Publications or use the eBook Search box on the Federal Depository Library website. You can also browse all of the available titles here. The eBooks are available in formats such as .mobi, .epub, and .pdf, so they can be read on various devices.
