Historically, scientists and managers in the field of weed biological control are not numerous, scattered worldwide, and have no formal organization or journal to communicate through. Since international cooperation is central to the practice of weed biological control, they convene at an international symposium every four years. The papers presented, besides describing the results of scientific studies and progress in ongoing programs, are the most comprehensive record of the wide range of weeds that have been targeted as well as the discussion on the theories and problems encountered in doing weed biological control over the last 40 years. A key product of each of the 12 symposiums held to date is the publication of a proceedings of the papers presented.

Unfortunately, many of the earliest volumes are exceptionally rare and even the most recent ones were printed in such small numbers that finding them today can be difficult. To make this wealth of information more readily available, the University of Georgia with support from the US Forest Service, Forest Health Enterprise Team has scanned the entire 12 volumes and is making them available on this website along with several cross linked indexes to simplify searching the 1345 articles of information they contain.
