Dividing Line Books is a New York rare book firm buying and selling materials across a range of subjects. Themes of experimentation and radicalism connect our inventory; we are drawn to works that disrupt prevailing conventions, whether social or aesthetic. Areas of focus include 20th-century counterculture, artists' books, queer histories, and poetries of the avant-garde. 

We're always interested in acquiring new material in these and other fields, and welcome inquiries of any nature. Though we don't keep open hours at our Ridgewood offices, we're happy to arrange pickups for local customers. To receive new catalogs and updates about in-person events, please consider signing up for our email list and/or Instagram account.
