Do you ever update your works?

Yes. Several of my eBooks made it to their third edition, and many have had one or more minor revisions along the way even if they haven't been updated to a full new edition. 

What's the difference between a revision and a new edition? 

  • A new edition means I've added substantial new material or made substantive changes to what's in the book. This is often because of a significant firmware update or an additional model change (e.g. D3 changes to D3s). New editions are identified by the first number in the version ID: 3.00 would be the initial third edition.
  • A revision generally only corrects errors or rewords passages people found confusing. Identified by the second number in the version ID: 3.01 would be the second revision of the third edition.

With electronic distribution of my books, the policies on updating are these:

  • I provide small revisions as a free update to previous purchasers for a limited period of time after they come out. An automated email is sent to all purchasers of the original with a new link for the update.
  • New editions are currently subject to a voluntary update fee (right now US$5). I send an email to all purchasers of the previous edition with an offer for the new edition that has a time limit to using it (typically 90 days). After that, a new edition would require a mandatory US$10 payment.
