Ramsay, G. W.; Crosby, T. K. (DSIR Plant Protection, Priuate Bag, Auckland, New Zealand) 1992. Bibliography of New Zealand terrestrial invertebrates 1775- 1985, and guide to the associated information retrieval database BUGS. Bulletin ofthe Entomological Society of New Zealand 11: 1-440. ISBN 0-9597663-4-0. This bibliography and its associated information retrieval database, BUGS, cover all the available literature concerned with non-marine invertebrates of the New Zealand subregion for the 210-year period 1775 to 1985. The bibliography lists approximately 14 500 references to information in about 950 periodicals and numerous books, as well as about 750 theses and projects of New Zealand universities. Literature concerning both endemic species and those which are adventive or introduced is included: many of the introduced species from the Northern Hemisphere and Australia are pests of agricultural and horticultural significance, and form a significant proportion of the New Zealand economic literature. The references are arranged in 19 independent sections, with each section being a separate bibliography: Coleoptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Residual Insect Orders, Arachnida, Residual Arthropoda, Annelida, Mollusca, Nematoda, Platyhelminthes, Protozoa, Residual Invertebrate Phyla, Aves, Mammalia, Residual Vertebrates, University Theses and Research Projects, and Pesticides. It is estimated that the coverage for all terrestrial invertebrates is 95% of the core literature and at least 60% of the popular literature. The introductory section includes a history of the development of the project and a brief review of computerised information retrieval. The standards used in compiling the bibliography and the BUGS database are set out and fully explained. A detailed guide is given with examples on how to search the database. The information content of references was recorded using a thesaurus of 4000 content descriptors; these descriptors are listed to demonstrate the depth of indexing of the information and the very wide range of topics and aspects it is possible to search, e.g., vertebrates as hosts or as predators of invertebrates, chemicals and other materials and techniques used in pest control, or medical or veterinary topics concerned with invertebrates. Searches may be narrow or wide-ranging, e.g., on a particular pest species or on all members of its family. The bibliography has no detailed subject index for the references, as this function is fulfilled by the BUGS database.
