ABAA, ABA, and ILAB — Professional Associations for Antiquarian Booksellers
The antiquarian book trade operates without the centralized regulation that governs many other industries. There are no licensing requirements to call yourself a rare book dealer, no mandatory inspections, and no government agency that certifies expertise. In this unregulated environment, professional associations serve as the primary mechanism for establishing standards, building trust, and providing recourse when transactions go wrong.
The three most important associations for the English-speaking collector are the ABAA (Antiquarian Booksellers’ Association of America), the ABA (Antiquarian Booksellers’ Association, UK), and ILAB (International League of Antiquarian Booksellers), the umbrella organization that connects national associations worldwide.
ABAA (Antiquarian Booksellers’ Association of America)
What It Is
Founded in 1949, the ABAA is the premier professional association for antiquarian booksellers in the United States. Membership is by invitation and approval — dealers must be nominated by existing members, vetted by a membership committee, and approved by the board. This selective admission process distinguishes the ABAA from organizations that anyone can join by paying a fee.
Membership Requirements
To qualify for ABAA membership, a dealer must:
- Have been actively engaged in the antiquarian book trade for a minimum of three years
- Be nominated by two existing ABAA members who can vouch for their expertise and integrity
- Pass review by the membership committee
- Adhere to the ABAA Code of Ethics
The Code of Ethics
ABAA members are bound by a code of ethics that requires:
- Accurate description of all material offered for sale
- Disclosure of defects — all significant condition issues must be described
- Return privileges — members must accept returns of material that does not match its description
- Fair dealing — members must not knowingly sell stolen property, misrepresent material, or engage in deceptive practices
- Dispute resolution — members agree to resolve disputes through the ABAA’s arbitration process
Why It Matters for Buyers
Purchasing from an ABAA member provides:
- A guarantee of description accuracy backed by the organization’s code
- Return privileges if the book does not match its description
- Recourse through the ABAA if a dispute cannot be resolved directly with the dealer
- An implicit quality standard — the vetting process screens out inexperienced or unscrupulous dealers
ABAA Book Fairs
The ABAA organizes major book fairs, including:
- The New York Antiquarian Book Fair (held at the Park Avenue Armory) — The largest and most prestigious book fair in North America
- The California International Antiquarian Book Fair (held in various Southern California venues) — The premier West Coast fair
- Regional fairs organized by ABAA chapters
These fairs bring together hundreds of dealers and provide collectors with unparalleled opportunities to examine rare books in person.
ABA (Antiquarian Booksellers’ Association, UK)
What It Is
Founded in 1906, the ABA is the oldest professional organization of antiquarian booksellers in the world. It functions similarly to the ABAA, with selective membership, a code of ethics, and organized book fairs.
Membership
ABA membership requires:
- Established presence in the UK antiquarian book trade
- Nomination and vetting by existing members
- Adherence to the ABA Code of Practice
ABA Fairs
The ABA organizes and participates in major UK book fairs:
- The ABA Rare Book Fair (formerly the PBFA Rare Book Fair) at various London venues
- The Firsts London fair at the Saatchi Gallery
- Regional fairs throughout the UK
ILAB (International League of Antiquarian Booksellers)
What It Is
ILAB, founded in 1948, is the international umbrella organization that connects national antiquarian bookseller associations from over 20 countries. ILAB membership comes through membership in a national association — you cannot join ILAB directly.
Member Associations
ILAB’s member associations include organizations in:
- United States (ABAA)
- United Kingdom (ABA)
- France (SLAM — Syndicat de la Librairie Ancienne et Moderne)
- Germany (Verband Deutscher Antiquare)
- Italy, Spain, Netherlands, Belgium, Switzerland, Austria, Scandinavia, Japan, Australia, South Africa, and others
ILAB Code of Usages
ILAB member associations adhere to a shared Code of Usages and Customs that establishes international standards for the trade:
- Fair and accurate description of books
- The right of return for books not as described
- Respect for intellectual property and cultural heritage
- Prohibition on dealing in stolen or looted material
- Cooperation with law enforcement and cultural property authorities
ILAB Search
ILAB maintains an online search tool (ilab.org) that aggregates listings from member dealers worldwide, providing a searchable database of books offered by vetted professionals.
Other Professional Organizations
PBFA (Provincial Booksellers Fairs Association, UK)
The PBFA organizes regular book fairs throughout the UK. PBFA membership is less selective than ABA membership, and PBFA fairs tend to feature lower-priced material — making them excellent hunting grounds for bargains and new collectors.
The Grolier Club (New York)
Not a dealer association but the oldest and most distinguished bibliophilic club in North America. Founded in 1884, the Grolier Club hosts exhibitions, lectures, and publications related to books and printing. Membership is by invitation.
The Caxton Club (Chicago)
A bibliophilic club similar to the Grolier Club, hosting events and publishing works related to book collecting and the book arts.
Fine Press Book Association (FPBA)
An organization for collectors and makers of fine press books, promoting the art of fine printing and bookmaking.
Practical Advice for Collectors
Always Check Credentials
Before purchasing from an unfamiliar dealer, check whether they are a member of the ABAA, ABA, or another ILAB member association. Most dealer websites display association logos, and the associations maintain searchable member directories on their websites.
Understand What Membership Does NOT Guarantee
Association membership indicates that a dealer has been vetted and adheres to professional standards. It does not guarantee:
- That every description is perfectly accurate (mistakes happen)
- That prices are fair (pricing is a matter of market judgment)
- That every book is authentic (even experts can be fooled by sophisticated forgeries)
Membership reduces risk; it does not eliminate it.
Use the Dispute Resolution Process
If you purchase a book from an ABAA or ABA member and it is significantly not as described, you have the right to return it. If the dealer does not cooperate, you can escalate to the association’s dispute resolution process.
Non-Member Dealers Are Not Necessarily Unreliable
Many knowledgeable and honest dealers choose not to join professional associations (the dues can be significant, and not every specialization is well-represented). The absence of membership is not proof of untrustworthiness. However, purchasing from non-member dealers offers less formal recourse if problems arise.
Book Fair Etiquette
When attending book fairs:
- Ask before handling expensive items
- Return books to their original position
- Do not bring food or beverages near the books
- Feel free to ask dealers questions — most enjoy sharing their knowledge
- Bring cash or a checkbook; some dealers prefer not to use credit card processing at fairs
