Alas… I don’t think I can say I learned while working on the best practices book that no matter how detailed you think you’ve reviewed your prose, some flubs will make it through.
Only because I learned that lesson a long time ago when I first got into publishing. I’ve seen notes from an author to an editor in a final print run, after all. (Thankfully, the editor wasn’t me!)
It doesn’t surprise me, then, that some errata has been noted, or that I’m the one reporting some of it. You can only hope that your mistakes are small, and the errata haven’t been all that critical to date.
That said, when you make an error, there’s no point running from it, and the two bits of errata that most bother me are both in the navigation chapter. I just gave a brief synopsis of one of the issues in the IDPF forums, so I figured I’d take a little more time to outline them both here.
And maybe take a look at a couple of additional clarifications we tried to make during the 3.0.1 revision, as grasping the in-spine and out-of-spine uses is proving to be generally confusing.
