Actually, what I love is the Open Library, which very politely digitized one of the early “no, we’ve never been there, but there’s a big market for it” guides to the Klondike gold fields, published in 1897. And made it free on the web.
There’s something just so incredibly civilized about being able to access an otherwise almost impossible to get hold of book by clicking a mouse a few times.
Also, I have written over 8000 words since November 1st. We’re still on the decrepit steamship, less than a day out of Skagway, and Our Heroine has already had more adventures (well, she is a long time ago and a fair distance away) than is good for her.
