How do they do it?

Nothing to do with 2600, but we were invited to share our frustrations, so here it goes. I've heard horror stories about 2002, but I never really believed them...until now! I have a new found respect for Reference Librarians. How do they do it?! All the information to be retrieved? All the silly questions to be answered? If this is the life of a Reference Librarian, count me out!
