ABAA
The Antiquarian Booksellers Association of America was founded to promote ethical standards and professionalism in the antiquarian book trade, to encourage the collecting and preservation of antiquarian books and related materials, to support educational programs and research into the study of antiquarian books, and to facilitate collegial relations between booksellers, librarians, scholars, and collectors. It is one of the 20 countries that is part of the International League of Antiquarian Booksellers and contains over 480 members. Each member must meet very stringent requirements to become a part of the organization.

ILAB
The International League of Antiquarian Booksellers is an organization that encompasses national associations of antiquarian booksellers around the world. It speaks for twenty nations and two thousand leading booksellers. Its sign stands for the integrity and professionalism of the trade worldwide.

Beginnings
The League (or ILAB, as it is often known among English-speakers; LILA among French) was founded in Amsterdam at a meeting of major European booksellers in 1947. It was born of the spirit of international co-operation and fueled by the determination to sweep away national differences that inspired the postwar world. Since that time its aims, objects and ideals have been adopted across the continents, and the ILAB network now extends into America, Asia and the Southern Hemisphere.

Objectives
The objectives formulated in 1947 are still little changed. Put briefly, they are to uphold and improve professional standards in the trade, to promote honorable conduct in business, and to contribute in various ways to a broader appreciation of the history and art of the book.
