From 1991: WELCOME TO TWIN PEAKS: ACCESS GUIDE TO THE TOWN.
This was the last of the official tie-in books published in that brief boom period when the series looked like a sure-fire certified hit rather than a show that scored well for only a few weeks, generated acres of press coverage and then started to fade before the first (short) season had even finished its run.
The Access Guide follows the tried-and-tested (although maybe not so much back in 1991) formula of writing an authentic looking tourist/ visitors guide to fictional local by incorporating and expanding on elements introduced on-screen.
This was written during the production of the second season because it incorporates elements like Owl Cave which, from memory, didn't become part of the mythos before Year Two.
This was published in the States and, unlike the other books, I don't think it earn't a separate British edition.
