There is a very large and very old book on my desk. It appears to be coming out of its binding. It has no documentation whatsoever to let me know who placed it on my desk, or how it got here. For all I know, it could have trundled in on its own (hee hee, like that old book could possibly jump onto my desk--maybe if it were 25 cm instead of 40).
I submit these kinds of happenings as the most annoying thing that happens to catalogers/archivists. The Mystery Thing. It will take me at least 20 minutes just to figure out who put it on my desk and why, and probably it will take even longer. And there are no guarantees that I'm even the person to have this book! Over my years as an archivist and librarian, this has happened to me a LOT. The best time ever, though (read: worst time ever) was when I walked into my office and found two huge paintings blocking my way to my desk. PAINTINGS. Which were almost as tall as I. Forty-five minutes later, I learned that someone "donated" them on the weekend, on the advice of my boss (who was not a librarian or archivist), who apparently stated "No problem! Our librarian will take care of them!" Even though we had a policy in place that we did not accept donations of artwork. Nor did we have proper storage for them. That was super-fun. I guess this book currently on my desk isn't nearly as bad as that, so maybe I shouldn't complain so much.
At any rate, I get really tired of these kinds of things. I like a mystery and all, but I have post-it notes on my desk. And pencils and pens. And I have an email address if you do not like writing with pens and pencils.
