But for some reason, I'm mostly ok with spines being largely informational. I understand that as a consumer browsing the aisles of a bookshelf, the text provided on the spine is there to give me specific bits of information about the book and the for something a bit more intriguing I may want to pick up one book or another and take a look at the cover or read through a few pages to see if this is something I may be interested in.
This is where I think the title becomes important. A catchy title can definitely lure a reader in. Not to say that a pretty spine won't, but I think a title can have as least as much weight in that regard. *shrugs. Just my two cents!
