If you are interested in Hamlet, this won't be of much use, but if you need geomechanics, then access to Engineering Village
may be just what you are looking for. Actually, the village offers cross database searching of the following: Compendex, EI Patents, GeoBase, NTIS and Referex.
For more detail, as OhioLINK describes it:
Compendex contains references and abstracts from some 5,000 engineering journals, conferences and technical reports covering all engineering disciplines. Online coverage is from 1884 to date. Ei Patents comprises millions of patents from the US Patent and Trademark Office and European Patent Office. GeoBase is a multidisciplinary database of indexed research literature on the earth sciences, including geology, human and physical geography, environmental sciences, oceanography, geomechanics, alternative energy sources, pollution, waste management and nature conservation. NTIS (National Technical Information Service) database contains citations to unclassified reports from U.S. and international government agencies such as NASA, the U.S. Department of Energy, and the U.S. Department of Defense. Materials cited date from 1899 to the present. Referex Engineering is comprised of six collections of full-text searchable engineering reference e-books.
