A little while back, I came across SearchCredible, a handy aggregator of the more academic search tools.
Though SearchCredible doesn’t allow you to search all the search engines simultaneously, it presents a sweet menu of options your students may not consider, or remember to consider, in their academic search lives.
Among the choices presented: Scirus for searching scientific information; the Directory of Open Access Journals, for free scholarly content; JSTOR, the subscription consortium that gathers a huge database of scholarly content; the well-respected Internet Public Library; Google Scholar; the international collection of primary sources in the World Digital Library; BUBL, the long-lived British Dewey-organized directory of academic materials; Intute, another academic British directory maintained by subject specialists; the collection of publications from the Oxford Journals; Project Muse; PubMed, providing biomedical and health content from the National Institutes of Health; the media-rich library of the Internet Archive; the WolframAlpha computational search engine; and the vast collections of The Library of Congress,
I hope the SearchCredible folks will consider linking to other subscription options (in addition to EBSCO and JSTOR), as well as a few other free tools:
- CiteSeerx (locate academic articles particularly for computer and information science)
- Ready, ‘Net, Go! (Tulane’s archival portal)
- OAIster (university archives)
- Academic Index
- INFOMINE (Scholarly Internet Resource Collections)
- Archives Hub archives of major UK universities
- Open Library free and public domain ebooks
A number of other academic search portals are listed in this post by Online Universities.
