To serve the customer anywhere, even "downstream"
Clicking on the e-book's title brings up a pop-up menu of options corresponding to the service options available for the book. All values in the pop-up menu can be dynamically updated by the publisher as they change, with no maintenance needed on the part of the party presenting the links (in this case the reviewer, BusinessWeek.com). The multiple options are simply a resource provided by the publisher, and not a means of controlling all linking related to a work. If desired, for instance, the page displaying the menu could exclude some options, or include their own relevant links.
To sell the customer exactly what's wanted
DOI-based linking from a personal email using the DOIs both for a book and for one of its components.
To help your content enhance the reader's experience
This excerpt from a McGraw-Hill ebook (PDF format) shows DOI-based linking between ebooks, even across different publishers! The blue hyperlink on page six links to another McGraw-Hill title, while clicking on footnote 14 on page seven shows linking from a textual note to a book published by Random House. Both links initially link to the book's bibliography, then out to the web.
To add power to direct marketing
In this promotional email for Anna Quindlen's A Short Guide to a Happy Life, published by Random House, links in the text of the email use the DOI system to redirect the reader to different services associated with the same DOI.
