Publisher description for Xper2

Identification of specimens (either extant or fossil) is a crucial point for any study in biology: inventory of biodiversity, phylogenetic studies, ecology etc. During most of the last two centuries printed dichotomous keys have been the main tool for practical identification. The knowledge representation and computing capabilities available nowadays and the common use of microcomputers has suddenly opened new perspectives. Biologists began producing computer-aided-identification systems in the late 1960s. The main difference between classical keys and these systems is the replacement of fixed sequences of questions on a printed key by a dynamic free multi-access system including images and documents to help the user.
