The Division of Reptiles and Amphibians maintains a collection that is worldwide in scope and is the second largest of its kind in the world. Presently, the research collections contain over 200,000 catalogued lots representing nearly a half million individual specimens, which includes nearly 500 primary type specimens with high resolution digital images. The average growth over the last ten years has been nearly 1500 specimens per year. Our auxiliary research collections include skeletal preparations (both dry and cleared & stained), frozen tissue samples, radiographs, kodachrome slides, digital images including CT scans, histological micro slides, and a large collection (over 250,000 records) of ecological vouchers collected from our Edwin S. George Reserve in Livingston County, Michigan. Additionally, .pdf versions of our valuable Field Notebook Collection and a collection of 37 audio tapes containing hundreds of recordings of anuran vocalizations has been digitized and can be accessed via the Division's webpage and the University of Michigan Digital Library. All of the above mentioned collections have been inventoried and the data associated with them have been entered into, and maintained in computer databases, with representative samples presented by the Digital Library.
