With student publishing projects in mind, and my own projects as well, I was recently reminded of one very cool site, Lulu.com , which lets you self-publish your own books in a way that books are produced and shipped ‘as needed.’ I have a dream of putting together many of the resources I’ve developed over the years into just such a book. One of the appeals of on-demand publishing, I think, is bridging the gap between print and digital tools. In an on-demand environment, I can more easily update time-sensitive writing, especially on technology topics. However, that does beg the question of what is a book, when it can change so easily! So many (fun) new problems to solve!
