The Master Record of Manuscript Collections serves as the basic guide to the division's collections. It consists of Master Record I, a brief checklist of all collections in the division's custody, and Master Record II, a more comprehensive catalog containing summary descriptions of collections and an index to the names and key terms cited in these descriptions. Neither Master Record I nor II has been published, but copies are available in reading rooms throughout the Library. In addition, Master Record II may be accessed through the Library's online catalog which is available on-site and through the Internet.
