The borrowed book

For the first time since joining LibraryThing, I have read a book that I do not own, and am confronted with the decision about whether to add to my catalog/ue a book that I have never owned. The reasons for doing so would be (a) to remind me that I have read it and (b) to record any comment or review. In principle, I have an 'association' with the book sufficient to qualify it for addition. But I am a hoarder, a jackdaw, a book-collector, dammit, and I love the idea of having a list of all the books actually on my shelves (all mine, my preciousss). Of course, I have already compromised this by listing books, reviewing them, and then putting on the 'out' pile and tagging them "export"; but at least I did once own them. Maybe I could start a new LibraryThing catalog for books I do not own, and copy the details across...; but then, the reviews would not count towards my total, and my narcissistic aim of getting on to the Reviewers Zeitgeist page would be set back. Aargh!

The book in question is The Fencing Master, which I found in a bookcase while on holiday in Somerset and read over the course of the week. It was very enjoyable. Maybe I'll add it and tag it "unowned" or "borrowed" or something. I'm going to run into the same problem with Riddley Walker...
