Today is the anniversary of the Treaty of Guadalupe-Hidalgo.  You can see an image of the Treaty on the National Archives website.

Per the National Archives, "the Treaty of Guadalupe Hidalgo, which brought an official end to the Mexican-American
War (1846–48), was signed on February 2, 1848, at Guadalupe Hidalgo, a
city to which the Mexican government had fled with the advance of U.S. forces. 
Signed on February 2, 1848, this treaty ended the war between the
United States and Mexico.  By its terms, Mexico ceded 55 percent of its
territory, including parts of present-day Arizona, California, New
Mexico, Texas, Colorado, Nevada, and Utah, to the United States."  In sum, Mexico ceded 525,000 square miles (55% of its pre-war territory, not including Texas) to the United States in exchange for $15 million ($313 million in 2006 dollars).

The library has several items specific to the treaty including:
