We have been dealers in rare and antiquarian books and manuscripts for more than 30 years and are based in NYC at 1510 Lexington Ave (by appointment only). Adam Weinberger is a member of the ABAA (Antiquarian Booksellers’ Association of America) which requires members to adhere to ABAA’s Code of Ethics.  We work with a large number of important collectors worldwide, rare book libraries, and other institutions, and can offer you immediate and top payment for your rare books and entire libraries.   We travel nationwide for important and interesting material.  Feel free to click on our about link or contact us directly. We always try to respond within 24 hours, and for valuable books, will furnish you with actual rare book auction records so you can understand the basis of our evaluation.

We Buy Old and Rare Books

Our speciality is in old and rare books, specifically early printed books before 1800 including incunabula, early Bibles (pre-1800), manuscripts, archives, natural history books, color plate books, books on travel and exploration and much more.  If you can provide quality photos of the book(s) binding and title page with date, we are often able to make offers based on those. Sometimes, books do need to be seen in person, and in that case we are happy to provide you with our company insured Fedex account for reverse charge (upon request)

Our evaluations are based on years of experience buying and selling rare books and manuscripts to many clients. We rely on common pricing resources such as the American Book Prices Database for auction records, German auction databases, and other essential rare book pricing reference tools and bibliographies. We believe in complete transparency and whether you wish to sell or not, are happy to provide actual comparable auction records so you can understand the basis of our evaluations.  We try to answer all enquiries within 24 hours.

We Buy Entire Libraries

We not only buy fine and important individual rare books and manuscripts , but also entire libraries, rare book collections, and archives.  We travel nationwide sourcing important material, offer immediate payment, and handle all packing and shipping arrangements.  Our size and facilities enable us to make en-bloc offers for quality collections.
