The collection includes drafts of his work, professional and personal correspondence, emails (both digital and in hard copy), notebooks, dream journals, heavily annotated books, lecture notes, teaching materials, photographs and ephemera. Several RBML collections already contain correspondence with Berman. For scholars, this collection will provide important new insights into the thought and work of a leading late-20th-century New York City intellectual.

The files are currently stored on his home computer.

His information file of clippings, excerpts, and ephemera. Each item is carefully documented as to its place and date of publication. Many of these documentary markings are in a highly abbreviated form for which there is a key. The clippings are from such publications as THE AMERICAN MERCURY, ARBEITER-ZEITUNG, AVANTI, THE DAILY WORKER, THE HERALD TRIBUNE, L'HUMANITE, KOMMUNISTISCHE INTERNATIONALE, LE TEMPS, NEW MASSES, NEUER VORWAERTS, RABOTNIK, and many others. Much of the material is in various western European languages, but the majority is in English. The collection is arranged alphabetically by country and within these broad categories the material is either in a rough chronological arrangement or is grouped around specific topics. The clippings are not mounted but are placed loosely in a series of folders. Also included are two volumes of Nomad's essays entitled: THE ANARCHIST TRADITION AND OTHER ESSAYS; and, POST-MORTEMS AND POST-SCRIPTS. These anthologies of printed essays and photocopies of typescript essays were compiled by Nomad in 1967.
