How do I check if an update is available for an ebook I purchased?
Check for UpdatesOn the first page of your ebook, in the lower left, click Check for Updates (see the image to the right; newer ebooks have a different cover design; the link is at the top of the first page). A few of our oldest titles lack a Check for Updates button; in that case, Contact us and we’ll take care of you. On the resulting Check for Updates Web page, you may see some (or occasionally a lot) of new material relating to the topic. You’ll also learn if we are planning an updated PDF in the near future. Updated PDFs that we consider to be minor updates are free, and you can download them from the Check for Updates page. In some cases, so much material will change that we’ll do a major new edition of the ebook and, in that case, we’ll let you know about the new edition and give you a link for buying it, usually with a nice discount.
