Incidentally, the International Code of Zoological Nomenclature is written in both French and English, with pages in French on the left side and pages in English on the right. A German edition is also available, though I do not have further information on it. The English and French versions are the authoritative ones. At present, separate Codes exist for plants (together with algae and fungi), animals, bacteria, and viruses. But a movement is afoot to combine all these Codes into one BioCode, whose text can be read on the Biosis website. If memory serves, the BioCode would apply mainly to taxa named after its starting date. This is a laudable goal and will be of particular service in computerized databases, but I'm not holding my breath until it is ratified by botanists, zoologists, and bacteriologists. Andrew K.
