The home page of the ABA has developed over the last year into a major resource. You need to explore around to find all the contents but will be well rewarded.
Some content is aimed at association members.
The Antiquarian Booksellers' Association of America was founded in 1949 to encourage interest in rare books and manuscripts and to maintain the highest standards in the antiquarian book trade. In support of these objectives, the ABAA has, among its other activities, promoted exhibitions of books and related materials and lectures on subjects of interest to book collectors. Members of the ABAA engage in the sale, purchase, and appraisal of antiquarian books and manuscripts. The Bookbinders' Guild is a non-profit organization comprised of professionals from all aspects of the graphic arts. Members include publishers, manufacturers, and suppliers involved in the creation of books and electronic media.
