Last week I asked what was the most popular book in your library- this week I'm going to ask about the most unpopular books you own. Do you have any unique books in your library- books only you have on LT? How many? Did you find cataloging information on your unique books, or did you hand-enter them? Do they fall into a particular category or categories, or are they a mix of different things? Have you ever looked at the "You and none other" feature on your statistics page, which shows books owned by only you and one other user? Ever made an LT friend by seeing what you share with only one other user?
I found 302 of my 1411 titles in LibraryThing were unique to my library. Many of my unique titles are from my genealogical books (especially surname-specific or locality-specific ones) or from my cookbook collection. (Most of those which were unique were locally published titles.) I have manually entered 222 titles; however, I often think creatively about which libraries might have a title before giving up! I have occasionally looked at the you and one other user page. In fact, I did tonight and discovered that my best friend and I share a book that we probably both purchased on a trip to San Diego a few years ago. I will have to say that I'm going to have to communicate with one of the others that I spotted on there who obviously shares an interest in Monroe County, Mississippi history and genealogy.
