Companies Will Use Content Directions’ DOI Registration Service



New York, NY, August 17, 2004 – Greenwood Publishing Group, one of the world’s leading publishers of reference titles, academic and general interest books, texts, books for librarians, professionals, and electronic resources, and Impressions Book & Journal Services, a leading composition and publishing services firm specializing in books and journals, announced their agreement with Content Directions, Inc. to implement Digital Object Identifiers (DOIs) to aid in the online marketing of Greenwood Publishing titles.


“Whenever someone encounters one of our DOI-enabled book titles anywhere on the Web, not just on our own site, they have instant access to all related titles by subject or by author, to additional information about the book, and to our shopping cart. We can also encourage viral distribution of our book titles onto author sites, online reviews and subject-specific web portals via CDI’s ‘Add this Link to Your Site’ feature.”


“Greenwood is excited to deploy MultiLinked DOIs as a way of helping our customers cut through the clutter of the Web to find our books.”

Ron Maas

Vice President of Planning, Greenwood Publishing Group

·      All Things Shakespeare -

·      Law and Business of the Entertainment Industries: 4th Edition -


“The DOI is one of the core technologies of the digital era. It has been widely used in journal publishing and now book publishers are taking advantage of it at an accelerating pace. We’ve teamed up with CDI because their MultiLink™ technology provides a sophisticated, effective foundation that uses the DOI to dramatically increase visibility, access, and sales for book publishers.”

Bill Kasdorf, President of Impressions
General Editor of The Columbia Guide to Digital Publishing


“We are especially pleased with the Greenwood success because it validates our commitment to offering DOI implementation through active partnerships with other companies. The DOI is something that benefits all the players in the value chain, and we are committed to working with all these parties, and sharing the revenues appropriately, so as to accelerate the adoption of this powerful business enabler.”

David Sidman, CEO of Content Directions, Inc. (CDI)



About the Digital Object Identifier (DOI®)

The DOI is an Internet-based system for identifying and exchanging intellectual property of all kinds (books, music, images, database records, product descriptions) and at any level of “granularity” (individual chapters, songs, articles, product components)It is the online equivalent of the UPC (bar code), and on the Internet it functions as a kind of “super-URL,” linking users directly to where they can buy the item, learn more about it, find related items, access related services, contact the publisher, etc. It also facilitates online transactions of all kinds, including e-commerce, rights management, and digital distribution.


Wherever the DOI is encountered – on Web sites, on Search Engines, within product reviews, within emails, and even within downloaded content – it always brings the user back to whatever information or services the publisher wishes to offer. Furthermore, these links are always up-to-date because they are served from a central DOI record maintained in a global directory (somewhat akin to the DNS system that routes domain names).
