Rare Book Collection

The library also possesses a 1,000-volume Rare Book Collection kept in secure, environmentally controlled compacted storage. The collection includes works by John James Audubon, John Gould and Edward Curtis.

The library participates in an institutional exchange program with other libraries, museums, and universities around the world. Current partners include more than 300 institutions from as near as the Cleveland region to as far away as China, Germany and South Africa. Exchanged titles include scientific and news-related publications spanning many languages and interests. Such exchange initiatives help to enrich our collection and distribute our original research to other institutions throughout the world.

Using the Library

The library's mission is to serve the ongoing needs of the Museum's researchers and curators. Although our books do not circulate to the public, the Library's collections are open for browsing and onsite reference. If you wish to view any of the library's holdings, please make an appointment in advance by contacting Museum librarian Wendy Wasman at (216) 231-4600, ext. 3222 or Research requests and inquiries from Museum visitors and the general public are also welcome by phone or email at any time.

The library also encourages individuals interested in library work to inquire about volunteer opportunities, internships or practicum projects. For more information please contact Wendy Wasman at the phone number or email address above.


The archives of the Museum was established in 1982 by the board of trustees for the acquisition, appraisal, processing, preservation, administration and unbroken custody of the non-current recorded information produced by the life and works of the Museum. It is the repository of recorded information (in whatever medium it may be found) with value for evidential, administrative, legal, financial and historical purposes for use in the future. Institutional records housed in the archives include administrative files of former directors and trustees; inactive departmental records, professional papers and correspondence of former Museum scientists, curators, and honorary associates; field notebooks, scrapbooks and clippings; files of Museum publications; and some memorabilia.

The Archives also house special collections concerning events or people loosely associated with the Museum. Material of this type includes the Henry Wood Elliott Fur Seal Controversy papers; records of the Blossom South Atlantic and Crile-White African expeditions, among others; biographical information on former directors, trustees, staff and students; an autograph collection of explorers and scientists; correspondence of a circle of 19th century botanists; daily sighting records kept by an amateur naturalist from Painesville; and the records of the Lake County Wildflower Club. Upon the Museum's merger with HealthSpace Cleveland and Eco-City Cleveland in 2007 and 2008, respectively, the archives of those institutions were added to the Museum Archives.
