Publishers' International ISBN Directory
The Publishers' International ISBN Directory (PIID) is published by the International ISBN Agency, London and by De Gruyter Saur, Berlin annually (usually October).
The 40th edition of the PIID lists approximately 900,000 prefixes from over 200 countries and territories. Its printed edition is structured in 2 sections:
- Geographical Section (volumes 1-4) providing names and contact details of over 800,000 active publishing houses arranged alphabetically by country and within country by name
- Numerical ISBN Section (volumes 5-6) listing all prefixes in numerical order.
The PIID is the most comprehensive up-to-date reference tool for the book-trade and the library world.
