The Manuscripts Division's collections are organized into two numbering systems. Most of these collections are open for use to anyone following a simple registration procedure.
Some collections are unprocessed and use is restricted.
Many collections are housed in off-site storage and require advance notice for use. Collection sizes range from one folder to several hundred boxes. Existing finding aids consist of box and folder inventories with brief introductory descriptions. Both types of collections are listed. In each list, click on highlighted collections for more information.
