The Christmas Truce of 1914
Wednesday, December 13, 2023, 1:00 pm - 2:00 pm ET

Just before Christmas in 1914, the Great War in Europe seemingly came to a stop. After the devastating First Battle of the Marne took place in September 1914, the situation on the Western Front evolved into static warfare. Both the Allied and Germans troops had dug into their newly built trenches and the fighting soon slowed down. As the weather turned colder neither side had the desire to launch a new offensive. So, on December 24, 1914, a series of unofficial ceasefires took place along the Western Front.

Resources at the National Indian Law Library 
Thursday, December 14, 2023, 3:00 pm – 4:00 pm ET 

There are 574 Federally recognized Native American tribes in the United States, all with their own unique governments and laws. Unlike the laws for many jurisdictions in the U.S., however, these laws can be difficult to find, if they are accessible at all.  Anne Lucke, Director of the National Indian Law Library (NILL), will discuss some of the reasons tribal law can be hard to find and the best resources for locating tribal law, including tribal websites, legal publishers, and NILL’s Tribal Law Gateway. 

Please note: This program is only being offered as a simultaneous online webinar. Please contact the Library to obtain webinar information for this program.

Law and Public Policy

The Interior Library Reference Staff maintains access to the Lexis Advance, Westlaw and PACER online databases. Departmental employees can visit the Interior Library or contact the Library by phone at (202) 208-5815 or via the Library's Questions and Comments form if they would like a reference librarian to conduct a work-related search in any of these databases.

Find Electronic Books and Journals By Title

To help you determine whether and where a needed electronic book or journal is available online, we provide a complete, searchable alphabetical list of titles. If you're not sure where to find a publication online, try this list first.

The list combines the full-text journals and other materials in all the database services to which the Library has access.

Also included are some single subscriptions as well as selected open access books and journals. Most entries include coverage dates, and all entries have links directly to the requested title.

Please direct your questions on database searching strategies to a Reference Librarian.
