The ICTV Ninth Report

      Congratulations to everyone involved in this monumental effort. Preparation of the Ninth Report has encompassed 6 years of work, and has involved hundreds of virologists putting together the most up-to-date internationally accepted taxonomy and nomenclature of all viruses. At 1327 pages, it is the largest report ICTV has ever published including 6 orders, 87 families, 19 subfamilies, 349 genera and 2284 virus and viroid species. It can be ordered from Amazon.
