The Engineering Library has just subscribed to two great new e-book collections: ENGnetBASE and NANOnetBASE. Both subscriptions include hundreds of e-books, particularly engineering handbooks. These are great reference sources, especially if you need to look up a quick fact, physical value, equation, or other piece of engineering data.
Right now the 2 collections are accessible as URL gateways. By mid- to late-September however, all of the individual e-books in both collections will be added to the Classic and WorldCat Catalogs.
