I thought I'd have loads of books on my shelves that Goodreads had never heard of but it doesn't happen all that often. And the little-known books don't generally get low ratings: if you're interested in something off the beaten track you'll have a reason for seeking it out and you'll know what might be good about it.

But by sheer fluke I just looked up a book that's been on my TBR pile for about 40 years and found a big fat zero - no ratings, no reviews.

You have to wonder how it ever got into their database. With a photo, even.
