Taxonomy lies at the uneasy interface between biology and logic. The processing
of information follows somewhat different rules in these two systems and the role
of taxonomy is to reconcile them as tidily as possible. To this end, the
International Union of Microbiological Societies
(IUMS) charged the International Committee on Taxonomy of Viruses
(ICTV) with the task of developing, refining, and maintaining a universal virus
taxonomy. The goal of this undertaking is to categorize the multitude of known viruses
into a single classification scheme that reflects their evolutionary relationships,
i.e. their individual phylogenies. The most recent report of the ICTV: "Virus taxonomy: classification
and nomenclature of viruses: Ninth Report of the International Committee on Taxonomy of Viruses. (2012)
Ed: King, A.M.Q., Adams, M.J., Carstens, E.B. and Lefkowitz, E.J. San Diego:
Elsevier Academic Press
is the standard and definitive reference for virus taxonomy.
