The main collection of the International Wine Research Database contains over 47,000 citations of wine literature from around the world. The articles abstracted in the database cover topics of both local interest and general knowledge of the wine industry. The bulk of the collection was compiled between 1988-2012. IWRDB began as a clippings file and many of the original clippings can still be accessed at the Sonoma County Wine Library. A significant number of the articles indexed in IWRDB are also available in full-text from the source publishers.
