Certificate & accreditation
The global standard for licensed libraries, publishers and bookshops
The PLEXO Certificate of Membership and Accreditation is an international passport of trust and compliance. Issued directly from our London headquarters, it validates the legal standing, authenticity and operational eligibility of member institutions across the global book trade.
Core benefits
What the certificate is worth
Accreditation is the document that opens the door — at customs, at a fair’s booking desk, at a consulate, and in front of a publisher deciding whether to trade with you.
Instant credibility and copyright compliance
Demonstrates to international publishers, distributors and authors that your institution operates in full compliance with copyright law and anti-piracy policy — with instant legitimacy through a transparent public verification portal.
25% discount at international book fairs
Official proof of entitlement to a guaranteed 25% discount on booth rental, floor space and exhibition stands at partner fairs worldwide, including Frankfurt, London, Bologna and Sharjah.
Visa facilitation and official delegations
The foundational document for PLEXO visa support and invitation letters, expediting entry visas for library directors and delegations attending international cultural fairs.
Exclusive access to PEX bulk orders
Only active certificate holders with a valid PLEXO ID may access and order global second-hand and clearance book pallets through the PEX bulk exchange.
Directory listing and visibility
Your institution listed on the official PLEXO interactive map and directory, making it discoverable to trade partners, universities and publishers worldwide.
