I just had a note from Roddy McLeod at Herriott Watt University telling me about a new service called EEVL Xtra , which is a new, free service, designed to put “The Hidden Web at Your Fingertips for Engineering, Mathematics and Computing.” It reveals articles, books, the best websites, the latest industry news, job announcements, technical reports, full text eprints,the latest research, and teaching and learning resources. EEVL Xtra cross searches (hence the X) dozens of sites, including many that index open access materials. Looks very promising.
