Berkeley Digital Library Project. Like the ADL, the University of California at Berkeley was one of the projects funded under the first Digital Libraries Initiatives. The collections at Berkeley are diverse, including botanical, zoological, and geographical data and photographs, more than 300,000 pages of environmental documents, and tens of thousands of images, mostly of California. The entire library is outlined in a "Quick Access to the Collections" matrix. All Berkeley-held information can be searched by keyword through a single interface based on Berkeley's Cheshire II search engine and Java scripting. Each result is listed at the bottom of an automatically generated collection hierarchy, showing its location, and all levels of the hierarchy are active links. In addition, collections have their own search and navigation tools, including simple search templates, dynamic maps, browsable categories, scannable alphabetical indexes for almost all searchable fields, and even a foray into image pattern matching based on "Blobworld" research. The TileBar interface used with the California environmental document collection is particularly innovative--it presents a visual method of assessing which part of a long document is relevant to a query.
