Odd jobs

Well finally finished my chemotherapy, and am making a vague attempt at contemplating a return to library work at some point. Having gone through the treatment, it does make it harder to take the, shall we say, trivial enquiries we get each day. As a way of returning on light duties, I did think I might try to take on some of the odder queries. For instance a lady telephoned the other day and asked when she could make an appointment to have her antiques valued. I did think that instead of explaining kindly that we didn't actually do that sort of thing and it was two years since the Antiques Roadshow had rolled in to town, I would set myself up with a green baize table and a Millers Antiques Guide. Can't be wrestling with tallboys though. Small items only.
I could also tackle some of those accumulated heaps of unidentified stuff that seem to hang around. I know all workplaces have them, but a library seems to attract a very special sort of detritus. For instance mystery account books with a balance in old money that no-one knows where to file. A plaque commemorating a forgotten anniversary, now slightly chipped in one corner. The planning documents for a building that was never actually built. A Heath Robinson style contraption with a slot at one end and a piece of wood at the other, which no-one now remembers the purpose of, but Doreen who used to work here and still comes in on Friday teatime might know something about.
Have you got anything odd in your library?
