Time travel

Every so often (three or four times a day) I wonder what job I'm really supposed to be doing. I think I'm systems librarian but I appear to be mistaken.

This lunchtime's "why me?" question:

"Why on earth have we got the 1988 Berlitz Guide to Yugoslavia?"

"I guess it might come in handy if 1988 comes back again."

Well, a stupid question deserves a stupid answer.
