I enjoy beautiful book covers: I present images of them sometimes on my tumblelog, and I subscribe to the RSS feed for the delightful Book Cover Archive. But we — I — should keep in mind this thought from Lynne Sharon Schwartz, who meditates on books she owns but hasn't read:
Others were just too gorgeously packaged to resist. Book jackets nowadays have become an art form, and browsing through a bookstore is a feast for the eyes. In some cases the jacket turns out to be the best thing about the book. I am not one to snub beauty, wherever it turns up. Yet I have come to distrust book jackets calculated to prick desire like a Bloomingdale’s window, as if you could wear what you read. The great French novels used to come in plain shiny yellow jackets, and the drab Modern Library uniforms hid the most lavish loot.
