This summer's issue of the Johns Hopkins CAAT newsletter is, in effect, a 20-page guide to information resources on alternatives and animal welfare. It comprises an introductory 5-page paper by Ken Boschert on ‘International networking and computer resources’; an inventory of ‘Electronic mailing lists of interest to laboratory animal specialists’; an annotated roll of ‘Institutional resources - North America’; lists of ‘Institutional resources - overseas’ and ‘Other sources of information’; an annotated directory of ‘Technology resources’ (largely commercial organizations etc in the United States which supply off-the-shelf alternative tests or material for use in alternative test systems); a short list by F Barbara Orlans and Amelia Tarzi of the ‘Top ten sources of funding for alternatives (US)’, and a 7-page article by Krys Ungar and David C Anderson entitled ‘An inventory of databases and other sources of information on alternatives to the use of animals in science and education’.
