It doesn't really "confirm" it, they have a ton of language in that book that's all "these are our best guesses about how some of these things might line up." It's a neat concept tho.



Since I've been waitin for a thread about this book to pop up tho, let me rant about one thing. A big deal in the JP release of this Zelda Encyclopedia was that it changed the Hyrule Historia timeline a bit, moving OOS/OOA out from in between LTTP/LA, and putting it after them, with a new Link. Which makes sense, since Link and Zelda interact in the Oracles as if they'd never met before. But the English translation fucked it all up, it copy/pastes the "this is the same link from LTTP" text from Link's Awakening for Link's origins, instead of the (roughly) "the boy who was traveling by horse" text from the JP edition. Every visualization of the timeline throughout the book is clear to place OOS/OOA as a separate time, distinct from LTTP/LA, but the one place where they said it explicitly was all fucked up. A real shame, makes it hard to trust a lot of other stuff in the book.
