A recent addition to the University of Wisconsin-Madison digital collections, the Zoology Museum (UWZM) Collection includes digitized versions of heavily illustrated biological journals, a few dated as early as 1859, and the majority from the first half of the 20th century, allowing visitors to page through the published observations of naturalists in the field. In addition to searching, journals can be displayed in a gallery view, so users can jump quickly to pages of interest. The Galápagos Collection, an important subcollection at the UWZM, includes skeletons, slides, pictures, books, and research papers collected and produced by UW-Madison scientists and researchers during ten expeditions to the Galápagos since 1969. The digitized portion currently is 20 volumes of materials, such as volume 10 of the National Geographic Society research reports: abstracts and reviews of research and exploration authorized under grants from the National Geographic Society, that includes a 1978 report on Galápagos tortoises by William G. Reeder and Craig G. MacFarland.
