This nice reference guide from Arizona State University's Noble Science and Engineering Library amounts to "an index to selected library and internet resources that contain chemical, physical, thermodynamic, mechanical, toxicological, and safety data." Starting with a list of suggested standard reference sources that may be found in most technical libraries, this reference guide goes on to include a vast reservoir of alphabetically listed library books and Internet sites where a user may locate specific information. From Abrasion Resistance to Yield Strength data, this index is quite comprehensive.
