Don't you hate it when you have the urge to read a 600 year old book, but you don't have it handy? I know, me too! Well, Chadwyck-Healey's Early English Books Online (EEBO) database, which can also be accessed through SFU's Library, has electronic copies of the earliest published English books. Anyway, I randomly picked a couple books and browsed through them, but they're really of no interest to me. Of course, you might find them interesting.
