Naturally, I posted my own response, defining in my terms what a Librarian is.
Librarian = Bibliographic expert.
Librarian = Research specialist.
Librarian = Hunter-Gatherer of the Information Savanna.
Librarian = Finder Of Secrets.
Librarian = Wielder of Reader Advisories.
Librarian = Party Organizer and part-time Hogwarts Professor Impersonator (true. I got a photo of me in a Hagrid outfit around here somewhere...).
Essentially, to me a Librarian is a key player in the Information Age, the professional who can store, sort, index and locate all forms of materials in all formats (print, audiovisual, electronic).
Don't sell us short.
