Email correspondent Leslie Shram just sent me a link to the "Bound for Success" exhibit that was at the Bodleian Library in Oxford, England, in 2009. While the exhibition is long gone you can still see images of 13 entrants and how they viewed the theme "water" when designing their books at the Guardian site.
If thirteen images aren't enough to satisfy, well you can get a copy of "Bound for Success" through Amazon for US$65.00. (It may be available elsewhere too, at a different price, but that's the first thing that came up when I googled it.) Thanks Leslie, for finding some fun eye-candy.
