We found ourselves making sample book pages this evening that looked kind of familiar. We wanted a generous outside margin, two columns of type on the large page, the columns up a little from center so as to make a generous bottom margin, and for that matter a generous top margin but not quite as large as the bottom. It started to seem pleasing but also familiar. On a hunch I turned on Google, and sure enough, we were roughly recreating the Gutenberg Bible. Well, if you're going to crib a design, crib from the best.
