Harper Perennial puts out limited-edition, pocket-sized editions of classics and contemporary classics as Olive Editions (list price $10). The cover art is minimal, but quite nice (check out this blog post to see the spines). I'm a bit of a sucker for series and having sets that match. If I'd known about these when Olive Editions debuted I'd probably have started collecting them all, but having only come across them this year, I don't think I'll both since they are limited and I assume that tracking down copies of some of the early ones would be a case in frustration.*
This year's Olive Editions are Bel Canto by Ann Patchett (great book - I should reread it), Brave New World by Aldous Huxley (I can't remember if I've read this one, which means I should get a copy from the library tout de suite), and Their Eyes Were Watching God by Zora Neale Hurston (this was our book club selection for September, but apparently I never got around to posting about it).
* but if anyone has an Olive Edition of The Unbearable Lightness of Being (2008) they want to rehome, I'm your (wo)man.
