The planning and initial expert consultancies for Ecocrop took place in 1991 and the actual work on the database started in July 1992. The database was developed by the Land and Water Development Division of FAO (AGLL) as a tool to identify plant species for given environments and uses, and as an information system contributing to a Land Use Planning concept.
The Index to American Botanical Literature has provided a service to the American botanical community for over a century, published initially in the Bulletin of the Torrey Botanical Club and subsequently in Brittonia. Beginning in 1886, when Elizabeth Britton of The New York Botanical Garden was editor, the Index has provided bibliographic data both on books and articles in periodicals. In 1999, the Index went to an entirely electronic format.
Mineral data for individual species are linked to mineral tables by crystallography, crystal structures, X-Ray powder diffraction, chemical composition, physical and optical properties, Dana's New classification, Strunz classification, mineral specimen images, and alphabetical listings of mineral species. There also are extensive links to other external sources of mineral data and information.
PubChem- The granddaddy of all free chemistry databases. Search over 8 million compounds by a variety of criteria. Although some PubChem records are linked into the primary literature through MeSH, most are not. But this doesn't seem to be PubChem's true calling. Instead, PubChem may well evolve into the world's largest online collection of molecular data sheets. Increasingly, the other databases in this list are cross-referencing their entries into PubChem. PubChem's entire database can be downloaded by FTP. CAS Registry are correct to see PubChem as the first real competition they've had in decades.
The SORA project (http://elibrary.unm.edu/sora) is an open access electronic journal archive and is the product of a collaboration between the American Ornithologists Union, the Cooper Ornithological Society, the Association of Field Ornithologists, the Wilson Ornithological Society and the University of New Mexico libraries and IT department. This archive provides access to an extensive Ornithological literature of international scope, and detailed material documenting the history of Ornithology in North America over the last 120 years. The content of this site includes the following titles: The Auk (1884-1999), The Condor (1899-2000), The Journal of Field Ornithology (1930-1999), The North American Bird Bander (1976-2000), Pacific Coast Avifauna (1900-1974), Studies in Avian Biology (1978-1999), and The Wilson Bulletin (1889-1999). Also available with browse-only capability is Ornithologia Neotropical; we hope to be able to index this journal soon, and include searching across its contents. We hope to be able to expand the content available as more Societies and journals join
The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 6.4 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 6.9 million records maintained by our collaborators.
