Scientists, in classifying invertebrate palaeontology, are obliged by the nature of the research to compare findings with illustrations and previous studies found in works dating back many decades. These classic works, when obscure or out of print, are difficult to obtain. To accommodate the needs of palaeontologists, Classic Literature on Invertebrate Palaeontology offers, on microfiche, material selected by specialists in seven major macro-invertebrate groups. Chosen are key materials, primarily from the 19th and early 20th centuries, and articles published in now-defunct journals or as monographs. These works include many of the first descriptions given of important species and contain numerous detailed illustrations.
- Palaeozoic Corals--early literature dealing with rugose and tabulate corals, including some references to stromatoporoids and bryozoa. Included are Goldfuss's Petrefacta Germanaie and works by Edwards and Haime, M'Coy and Quenstedt, and others. Geographic coverage includes North America, Europe, and Russia. 17 titles edited by Colin T. Scrutton.
- Crinoid Literature--spans over 100 years of key works on fossil crinoids, the earliest being J.S. Miller's monograph of 1821. Emphasis is placed on palaeozoic crinoidea through systematic treatments necessary for crinoid taxonomy. Geological surveys include locations in Europe and North America. 14 titles edited by N.G. Lane.
- Trilobite Works--a selection of 29 classic works containing numerous taxa described for the first time, predominantly in the early 19th century. Several illustrative plates are included. Editors: C.P. Hughs, A.T. Thomas, and H.B. Whittington.
- Mesozoic Bivalves--81 titles that are an indispensable basis for research on bivalve classification. Covers areas of Europe, North and South America, the Middle East, and Africa. Edited by N.J. Morris.
- Graptolite Literature--pre-1926 literature covers major early developments in graptolite studies and begins with Barrande's 1850 work offering the first accurate description of generic morphology. Included are contributions by James Hall, Lapworth, Tullberg, and others. 24 titles edited by R.B. Rickards and D.C. Palmer.
- Mesozoic Brachiopods--six important but obscure monographs including difficult-to-locate French and German works such as those by E. Eudes-Deslongchamps, Schloenbach, and Quenstedt. Contains rare illustrations. Edited by Ellis Owen.
- Mesozoic Ammonites--includes d'Orbigny's volume on the Jurassic cephalopods of France, a report by Forbes on fossil invertebrate in Southern India, and works by Grossouvre, Koenen, Kossmat, and Schlüter. Nine titles edited by M.K. Howarth.
