The Rare Book collections are organized into rare books of general subject interest and around a central theme, subject, or author. The oldest printed book is dated 1478, but the collection contains facsimile editions of many classic works.

The general Rare Book collection contains many books of historical interest in agriculture, the book arts (including books published by fine presses), botany (including herbals), history, philosophy, typography, and zoology.

Collections developed around a central theme or author include:

• Carl Woodward Collection of Early Agricultural Publications
• Commercial Pattern Book Collection
• Personal Library of Fritz Eichenberg
• The Wilbur Doctor Merrymount Press Collection
• Edna St. Vincent Millay Collection
• The Poetry Collection
• Ezra Pound Collection
• The Pym Randall Press Collection
• Edwin Arlington Robinson Collection
• Walt Whitman Collection

All the books in the Rare Book collection are cataloged and can be located in the ExLibris with their respective collection designation before the call number.  Rare Books do not circulate.
