Historians often overlook a wealth of information on historical events published by the U.S. Government. Much of this material is available in libraries around the country in print form (Including the Alkek library) and, increasingly, in online formats.
Many of these fit the definition of a primary source, as defined in the tab at the top of this page.
More information about Government Documents resources is available with information about how to access the collectionsand how to contact the staff.

There are two cumulative indexes covering 1861-1899 and 1900-1918. The organization of the series is generally chronological. Each volume has a subject and author index. The title changes slightly over the years but, all volumes are on the 5th floor of the Alkek Library at the call# in the link above.
