Re: the whole, ‘is Essentials a new edition or what’ debate. Just wanted to get a piece of pedantry off my chest.
er·ra·tum // ( -rä t m, -r -)
n. pl. er·ra·ta (-t )
An error in printing or writing, especially such an error noted in a list of corrections and bound into a book.
re·vi·sion // (r -v zh n)
1. The act or process of revising.
2. A revised or new version, as of a book or other written material.
I think there’s a whole bunch of revising going on that people are caalling errata. Errata is never to be criticised as far as I’m concerned. If it’s wrong, it needs to be corrected. Revisions, on the other hand, are all subjective. You can agree with them or not.
I’m not making any judgement here, just getting the language right. Carry on.
