The Tonopah and Tidewater Railroad Records (1905-1977) contain correspondence, purchase requisitions, bills of lading, freight reports, and waybills. Also included are a ledger book, a rubber stamp, and a booklet, "Diagrams of Locomotives and Tenders." Incorporated in 1904, the Tonopah and Tidewater Railroad operated for 35 years, connecting Ludlow, California with Beatty, Nevada by way of Death Valley on the Santa Fe Railroad main line. The records are concentrated on the later years of the railroad from 1930 to 1940.

The Mavis Eggle "Books as They Were Bought" collection provides a broad overview of printed material from the 1780s through 1949. Gathered by book collector Mavis Eggle, the collection serves as a social history of books, newspapers, and ephemera. Physical characteristics of the books include a variety of printer's marks, publishers' bindings, bookplates, and early subscription libraries. The collection's titles are a diverse and creative gathering of poetry, children' literature, religious texts, broadsides, newspapers, and popular fiction. Together, the items in the Mavis Eggle "Books as They Were Bought" collection illustrate changes in literature, printing and publishing, advertising, and book history over a time period of more than 170 years.
