McGraw-Hill Digital Engineering Library










Content made available either by subscription or pay-per-view



New York – March 15, 2005 – In the engineering field where precision is critical, professionals now have one of the most precise and effective online reference tools available to them. It’s McGraw-Hill Professional’s Digital Engineering Library (DEL), which is built with a search capability powered by Content Directions, Inc. (CDI), the leading commercial digital object identifier (DOI) Registration Agency.


DEL is a new service providing premier engineering information on the Internet, delivering over 4,000 articles derived from 150+ outstanding McGraw-Hill engineering titles. This online reference is uniquely structured around 12 major areas of engineering and more than 500 topics. Powered by CDI’s technology, every content item in DEL has been assigned a DOI, which functions as a kind of “super URL” or web address. DOIs provide users with pinpoint access to the exact information they need.  Rather than merely directing users to a publication index, DEL uses the DOI to bring the user directly to the desired object and anything related to it, including the various ways that the content can by acquired (pay-per-view purchase, subscription, etc.).

 “We are proud to offer the first engineering resource on the Web to be enhanced with CDI’s DOI standard,” said Scott Grillo, vice president/director of Digital Product Development, McGraw-Hill Professional. “McGraw-Hill’s content, combined with this technology, gives engineering professionals exactly the information they want, when they want it.” McGraw-Hill was one of the first publishers to take advantage of DOI technology and apply it to materials in both print and electronic formats.


 “McGraw-Hill’s latest use of DOIs is one of the first that combines a pay-per-view business model and a subscription-based one,” explained Hugh Brownstone, CEO of Content Directions.   “For subscribers, we anticipate that DOIs’ enhanced discoverability and improved user experience will lead to greater use and higher renewal rates, especially among libraries and other institutional users.”


To see examples of how DOIs are used in other McGraw-Hill products, visit the McGraw-Hill Book Catalog at and click any of the "Subjects" listed at the left, then mouse over "See the DOI for more info" under each book.
