I am a librarian.
What does a librarian do? Works with books, looks things up, helps you find things out.
Information organization and retrieval. All the jobs I've held since college (with the
exception of working as a mail handler at the post office) have involved varying degrees of
those two things: organizing given information and presenting it when asked. I seem to have
a natural talent for this: I've always liked being around books, and poring through them trying
to turn up some particular fact.
