First in a hundred years
Recently I had occasion to borrow and read a little book called The Battle of Dunbar, published in 1900. The book's prose wasn't particularly engaging, but its construction was of interest. You could feel the typed letters with your fingers and the pages smelled a little moldy but the best part came when I reached the middle of the book and discovered unopened pages. This means that the edges of some pages were sealed together and hadn't been cut. I had to open them using a sharp implement (though I've just discovered you're supposed to use a playing card and run it along the inside of the pages. Oops.) If you'll recall, in The Great Gatsby, Nick discovers Gatsby hasn't read any of the books he owns, because none of the pages have been cut. So what my discovery indicated was that in over one hundred years no one had read this entire book (and it was by no means long--40 pages perhaps). It felt awesome to be the first person to separate those pages and see those words. And this is why I'm a writer: because I adore book moments like these.
