MIT Press' new digital distribution portal: CISnet

My first book is at MIT Press, and they've made the first chapter available for free online ever since launching the book. (Not coincidentally, when people cite Tracing Genres through Organizations, they usually seem to cite Chapter 1.) But MIT Press has now made that book and many others available through CISnet. This is from the email they sent me:

As part of the MIT Press’s ongoing exploration of digital publishing opportunities, we are launching CISnet, a new electronic collection of MIT Press titles in computer and information science. I write to let you know that one or more of your books is included in the collection. CISnet, the MIT Press Computer and Information Science Library, can be found at http://cisnet.mit.edu. It is the Press’s second library of e-books in a single subject area and follows the model of CogNet, our popular online collection in the cognitive sciences. CISnet currently contains about 170 titles hosted in PDF by technology partner Tizra, Inc. It offers the ability to read these books from any Web-enabled computer and to search within them as well as across the collection.

I've cruised through my book online, and it looks pretty good. They're shooting for institutional subscriptions, but you can buy individual ones too. Check it out.
