So bookcase 51 has gone the way of bookcase 49 - there are no books on either I want to read (they are both small bookcases with around 3 books on). I'm sure in the next year something will turn up on these bookcases and I will keep looking every time I go to the library.
In the meantime it's on to bookcase 52 which marks the start of a new section, Large Print. This particular bookcase seems to have a fairly unchallenging set of "light" reading so it was a bit of a challenge for me to find anything at all which I wanted to read.
In the end I picked A Christmas Grace by Anne Perry which looks to be some sort of historical mystery. I hope I manage to finish it!
