This is one of the several sites that provide in-depth evalutions of medical WWW sites. The evaluations are selected by a group of physicians, librarians, nurses, and medical administrators. Some sites include several reviews, and visitors to the site can post additional comments. This directory has a bias toward systematic and taxonomic information. The sites search engine does not just search for titles, but searches the full text of many of the documents.
Updates are very current and rather substantive.
The conference information is particularly valuable. The Biosis site also includes an index to organism names. It includes two huge directories of veterinary resources and animal resources developed by Ken Boschert a Veterinarian at the Washington University's Division of Comparative Medicine. NetVet breaks down information by career, education, specialties, organizations, directories, e-lists, publications, images, government and commerce. Electronic Zoo has similar breakdowns, and both sites are searchable.
