I've come to the realization that you need to pull from a bunch of different sources to get a good enough background in the domain of electrons to start building a project you want to see realized, and that mastery in this domain is probably a journey that can be measured in decades.
The first two editions had quite a few errata, but there is an online page for them:

I don't recommend the Kindle version though, the formatting is really lacking.
