ABF meaning in Academic & Science ?

The Danish Antiquarian Booksellers' Association (Danish: Den Danske Antikvarboghandlerforening ABF) is the premier Danish organization of professional antiquarian booksellers. It is the oldest league of antiquarian booksellers in Scandinavia as well as one of the oldest of its kind in the world, only preceded by the English ABA and the French SLAM. The purpose of the association has always been to standardize the descriptions of books, preserve and develop the trade and thereby the general recognition of it, represent the trade as an assembled unity in public and official contexts, making requirements for the members in order to raise the standard and generally uphold the trade. All ABF members are bound to adhere to the ILAB Code of Ethics.
