Here is one of the first large-scale scientific projects based on HyperCard: a multi-stack manual on North American Trilobites made by Dr Robert E. Sloan, professor of paleontology at the University of Minnesota. Trilobites are a class of extincted marine Arthropods of the Paleozoic Era.

The stack uploaded on this page covers anatomy, classification, paleoecology, and evolutionary history of Trilobites of the Ordovician period, about 450 million years ago. More details about this project on the preface card ("Stack Info" button).

Version 0.81 of Ordovician Trilobites, still experimental back then, has been superseded by the final version the following year. Other stacks have rapidly been published afterwhile on Cambrian Trilobites, Agnostid Trilobites and Silurian to Permian Trilobites, as confirmed by Dr Sloan's autobiography (companion PDF, p.66). All together they form a true paleontology textbook, deserving respect and consideration. My only reservation concerns however the lack of bibliography on this test edition.


If anyone has the final version of all these four stacks, please upload them on the Garden for archival purposes. These witnesses of the early days of digital scientific communication must not be lost.

Come to think of it, Dr Sloan's stacks on Trilobites are not the only ones I would like to see uploaded on this website. Page 66 of his autobiography also mentions some other HyperCard achievements of great scientific interest. So why not upload his whole production here if possible?
