Antiquarian Booksellers’ Association of America – ABAA
The ABAA is an association of our nation’s most experienced and knowledgeable antiquarian booksellers. It promotes ethical standards and professionalism in the rare book trade and sponsors two large annual antiquarian book fairs. ABAA members are sworn to a strict code of ethics. In an era when every Tom, Dick or Harry is a bookseller, it is easy to be disappointed by those who have little experience, especially when buying online. No other organization guarantees the knowledge, experience and ethics like the ABAA of which Tony Weller and Joan Nay of Sam Weller’s Rare Book Department are member and associate member respectively. The ABAA web site isn’t as large as ABE’s because only accredited sellers are permitted to list books there. But this is why the ABAA site can be used with confidence. When expertise is important, the ABAA’s web site is the place to start.
