Dividing Line Books is a New York rare book firm buying and selling materials across a variety of genres. Themes of experimentation, transgression, and radicalism connect our inventory, and we are drawn to works that disrupt rather than reinforce prevailing conventions, be they literary, social, aesthetic, or otherwise. Developing specialities include 20th-century counterculture, literature of the psychedelics movement, poetries of the avant-garde, and artists’ books. 

We are always interested in acquiring new material in these and other fields, and warmly welcome inquiries of any nature. Though we do not keep open hours at our Ridgewood office, we are happy to arrange in-person pickups for local customers. The rest of our sales are conducted via mail-order and through occassional book fair appearances. If you haven't already, please consider signing up for our email list, which is the best way to get first peek at our freshest and most exciting materials.
