So, thanks to an interesting query that needed following up on,* yesterday I learned that THE HISTORY OF THE HOBBIT is now available in electronic format -- specifically, as a Kindle book.
Although the write-up on that page makes it seem as if it's just Volume I that's available (MR. BAGGINS), the cover image shown is the correct one: this electronic file actually includes both MR. BAGGINS and RETURN TO BAG-END. In fact, it's the revised and expanded single volume edition (THE HISTORY OF THE HOBBIT) released by HarperCollins in 2011.
I'm excited to have the book be readily available to folks with e-readers. I'm old school enough myself to prefer paper books for most of my reading, when that's an option, but know a lot of folks who do most of their reading these days on the Kindle or their i-Pads. And at about a thousand pages for $12.74 it's not bad for scholars on a budget.
Mostly, though, I'm just glad to have another venue in which to share my enthusiasm for Tolkien in general and THE HOBBIT in particular.
