OK sure. We've all got our little preconceived notions about what librarians are and what they do. Many people think of them as diminutive civil servants, scuttling about "Sssh-ing" people and stamping things. Well, think again buster.
Librarians have degrees. They go to graduate school for Information Science and become masters of data systems and human/computer interaction. Librarians can catalog anything from an onion to a dog's ear. They could catalog you. Librarians wield unfathomable power. With a flip of the wrist they can hide your dissertation behind piles of old Field and Stream magazines. They can find data for your term paper that you never knew existed. They may even point you toward new and appropriate subject headings.
People become librarians because they know too much. Their knowledge extends beyond mere categories. They cannot be confined to disciplines. Librarians are all-knowing and all-seeing. They bring order to chaos. They bring wisdom and culture to the masses. They preserve every aspect of human knowledge. Librarians rule. And they will kick the crap out of anyone who says otherwise.
