Puerto Rico, American Guide Series volume, 1940
Each American Guide to a state or territory, such as this one for Puerto Rico, covered the region’s history, geography, economy and culture. The books included maps, drawings, photographs and tour itineraries. The goal of the project was not just to employ writers, but also to stimulate local economies by encouraging tourism.

A Library for Congress
Thomas Jefferson believed "there is ... no subject to which a member of Congress may not have occasion to refer," and his broad approach to book collecting shaped the holdings of the Library of Congress. The library was created for members of Congress as a resource for their work—by extension becoming the nation's library and the world's largest repository of knowledge. In addition to politics, history, and law, its holdings encompass philosophy, poetry, classical literature, art, the natural sciences, and popular fiction.
