This CD-ROM, published by ETI and the Harrison Zoological Museum (UK), contains a treatise on all 119 species of bat known from the Indian subcontinent. With over 1000 illustrations, drawings and videos, this CD-ROM gives a detailed understanding of the morphology, variability, geographical distribution, biology, ecology and conservation status of each of the species. Three different illustrated computer-aided keys facilitate the identification of the species. All text is hyperlinked: an illustrated glossary defines specific scientific terms. The bibliography includes over 600 references from journals and books and a gazetteer is added (with illustrations) to specify the ca. 1400 localities mentioned in the text. This CD-ROM is an excellent introduction to the Indian bats and belongs in any modern scientific library.
