Good friends, My books are available in multiple formats (PDF, epub, etc) for free download under the Creative Commons license. It's perfectly fine and legal for you to download, copy and share them, so long as you observe the niceties of passing along the license (although PDFs of The Pains and Cheap Complex Devices that were not produced by me are in violation of the license -- but that's nothing to get too bothered about, especially if you get the "official" PDFs from the link that Udhay send round earlier, which are the "authorized" versions). You can find all my books on the net if you look around.
Note that I'm not forwarding the link. This is because I honor the Silklist tradition of not top-posting ;^) Also note: I no longer host the free versions on my site, nor do I give pointers to people about where to find the free versions. I prefer that people buy copies; I get money that way. If people find free versions, more power to them. I hope they like 'em. But it's not in my interest to promote them. Let my fee books promote themselves. I promote the versions that people purchase, whether from Amazon or Barne & Noble or even from me, directly. Anyway, I make this observation to Silklist, given that this is the kind of thing we often talk about here. In fact, if I remember right, I first came to Silklist by way of Christopher Kelty, who writes about the theory & implications of free & open-source, etc. If you do download my books for free, and you do like them, I think it would be a nice gesture for you to post a review somewhere -- whether Amazon or Goodreads or your blog. Of even just a tweet. If you don't like 'em, of course, the appropriate thing would be for you to forget you ever saw them ;^) I would be happy to engage with y'all on the list about my experience-based attitudes (philosophy?) re: "free" books, "intellectual property", Creative Commons, etc. Regards, jrs
