The material in this collection was originally housed in binders in Barney Rosset's New York apartment, and cover his personal and professional endeavors as a radical publisher, intellectual, and overall man of letters. It consists of writings, letters, photographs, interviews, films, catalogs, publishing files related to both Grove Press and Evergreen Review, and extensive biographical information on Rosset. The entire collection has been rehoused into archival quality boxes and folders. Each binder had been labeled, generally with some sort of topical or chronological designation. In most cases the binder labels will be retained as file titles, and the subdivisions within binders have become folders and retained, to a great extent, the titles assigned to them by the creator. In some cases the staff of the RBML altered or elaborated on existing folder titles for general clarity and ease of research. In some cases, the collection contains both original and typed (or transcribed) copies, the latter often taking the form of computer printouts that were originally held in binders marked "Master" or "Master Disk" to indicate their contents were on computer disks. These original binder titles have been kept throughout the finding aid.
