We have 32,476 books. Well we might have.
But as there was no system of checks and balances, no QA, no spreadsheets listing categories, no double-checking of other people's additions... as the entire process was conducted on random bits of scrap paper with a bare minimum of discussion (we were all counting, see, and we'd have lost our places), and as we don't know (a) how many books are currently on loan because the system doesn't readily give us those sort of figures and (b) how many we are supposed to have all things being equal, we could have just as easily made up a rough figure and stayed in bed (separate beds... we're not 'that kind' of library).
But here's something to think about next time you're ploughing through a book you're not really enjoying: with more that 9,500 novels in our branch, IF (and you'll see, a rather big 'if') I read one every day it would take me 26 years to read them all. But also, I would never read them all - because we get more than 7 new ones every week so the incoming would exceed the outgoing.
