The Searchable Ornithological Research Archive (SORA) is an excellent resource for professional and amateur ornithologists alike. SORA is an online journal archive produced jointly by the University of New Mexico, Association of Field Ornithologists, Cooper Ornithological Society, American Ornithologists Union, and Wilson Ornithological Society. The "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." At present, SORA contains the following journals: The Condor (1899-2000), The Auk (1884-1999), The Wilson Bulletin (1889-1999), The Journal of Field Ornithology (1930-1999), Studies in Avian Biology (1978-1999), Pacific Coast Avifauna (1900-1974), and the North American Bird Bander (1976-2000). A multitude of downloadable articles can be located by browsing the contents of different journals, or by using a search engine with fields for Keyword/Subject, Title, Author, and Years.
