A woman in my book group has been looking for a book for the last 5 years. She remembers several things about the book, but she knows she can recognize it by its cover. Everyone in the group has tried to find this book at some point and today was my turn. I created a link from the Advanced Search results page to another page displaying all the cover images from those same books. Yippy!! Now in just a couple of minutes, my friend can find the book she's been looking for.
It seems that all enhancements to FictionDB come from someone's need to get the same data in a different way. Hopefully, my friend's request can help you find the books you've been looking for :)
