If you have a peek at the Google Search page, you'll see that it features a Sherlock Holmes motif. That's because May 22nd is the birthday of the creator of Sherlock Holmes, Sir Arthur Conan Doyle. As I've mentioned before, you can download excellent human-read versions of The Adventures of Sherlock Holmes from Project Gutenberg, as well as the normal text versions. Download them and enjoy!
Oh, if you want to download a bunch of them quickly, try using curl:
