Looking for pithy thoughts about early modern printing? Wynken de Worde is now on Twitter! You can follow wynkenhimself or just scroll down to the bottom of the right sidebar to see his feed. And it's not procrastination. It's the expansion of his unerring instincts for cross-referencing and promotion that made him the great printer that he was. Um, I mean, is. (Keeping track of the time-period switching and the gender-changing is trickier that you might guess.)
And so that you can more fully appreciate the joke in the title: the sheets in question are of course not sheets on your bed, but the sheets of paper that are the basic unit of measurement for early modern printers, who thought of books--and the cost of books--in terms of the number of sheets it took to print them. Funny, right? That Wynken, he's got a sense of humor.
