The Historic Map Collection at the University of Delaware Library comprises over 800 published maps dating from the sixteenth to the twentieth centuries. The majority of the maps depict North America during the eighteenth and nineteenth centuries, but the collection also holds early maps of the New World, maps of Europe, Asia, South America, and Africa, as well as world maps and atlases. Although this is a comprehensive collection, Delaware state maps, maps of the Middle Atlantic region, and charts of Delaware Bay make up the most extensive part of the collection.
Prints, Photographs, and Images at the University of Delaware Library are managed in collection call number series and are indicated by a "PPI" placed before the collection number.

The majority of the seed catalogs belonging to the University of Delaware Library are cataloged through an inhouse card file; only limited titles can be accessed through DELCAT. This list supplements the inhouse catalog and the limited DELCAT records, providing access to uncataloged holdings. Researchers should visit Special Collections, and consult both DELCAT and this finding aid in order to see the Library’s entire holdings of seed catalogs.
The University of Delaware Library Special Collections Department houses an extensive collection of trade catalogs and advertising ephemera produced in the United States from the middle of the eighteenth century until the present day. The collection's strength is in its diversity. Rather than focusing on one type of product or industry, the Library's goal has been to acquire broadly and develop a wide range of catalogs that support research and teaching in a variety of disciplines. The trade catalog collection also complements the Special Collections Department's traditional strengths in the history of horticulture, science and technology, printing and publishing, and the book arts. Companies selling printing supplies, agricultural implements and nursery stock, type founders, publishing companies, and booksellers are particularly well-represented as are the catalogs of Delaware businesses.
