The
Field Studies Council recognised the widespread need for identification guides soon after its inception, and has since established a long tradition of publishing such material. Many of these were written by teaching staff writing their own keys to fill obvious gaps in the available literature. However, it became increasingly apparent that a change in approach was needed. Too few guides were available which were usable by those with little previous experience. Many groups of plants and animals appeared to be neglected. The FSC initiated the AIDGAP project in 1976, with input from an advisory panel which included a range of organisations such as the
Linnean Society, teachers in secondary education and professional illustrators. The two main objectives adopted by the panel were first to identify those groups of organisms regarded as 'difficult' due to a lack of a suitable key, and second to investigate ways of alleviating the difficulties of identification for each group. The panel also decided to incorporate a 'testing' stage during which the identification guides could be revised and improved. In practice today, AIDGAP guides are produced as 'test versions', which are then circulated to at least 100 volunteer 'testers', drawn from a wide range of backgrounds. ==Titles in the AIDGAP series==
