Located in Butler Library, the Rare Book & Manuscript Library (RBML) is Columbia's principal repository for rare and unique materials, with holdings that span four thousand years of recorded knowledge, from cuneiform tablets to early printed books and born-digital archives. Each year RBML welcomes thousands of researchers and visitors to their reading room, exhibitions, programs, and classrooms.
The student strikes of this era, in particular that of 1968, represent the main focus of the collection, although other issues and many voices are expressed. The collection contains material authored by Columbia University administration, faculty, students, as well as non-affiliated organizations and individuals.
