About RBML


The Rare Book & Manuscript Library is Columbia University’s principal repository for special collections. We collect, preserve, describe, promote, and provide access to the material evidence of diverse individuals and activities in alignment with the University’s research and teaching mission. We build and steward deep collections in select subject areas and connect them to a global audience through reference, teaching, exhibitions, publications, and public programs.
