The Arizona-Sonora Desert Museum (ASDM) has been quite the authority on this unique region of the United States for well over 50 years. With funding from the Institute of Museum and Library Services (IMLS), they have been able to create this extensive digital library which documents the area's landforms, animals, plants, minerals, and landscapes. On the homepage, visitors can search the entire collection, and they may also wish to browse the collections, which include sections like "Animals", "Minerals", and "Biotic Communities". The "auto-suggestion" feature is a nice touch, as it suggests possible species and names, such as "salamander" and "eagle". Each entry contains a high-quality photograph, a detailed description, and other relevant information. The site also includes a section of "Kids' Pages", a FAQ area, and an area for those who might wish to contribute to the project.
