So You Want To Be A Librarian?

Interesting perspective on librarianship in this film. How many librarians actually work with books and people these days? I'm not sure the profession has changed that much. However, the tools that we use to do our jobs have.
Love this footage!

While the daily tasks may have changed, the principles of the modern library are the same. Academic, Public, Special, Digital, Archival or otherwise, the ability to deal and communicate well with people should always be at the core of the profession.
They had cataloguers, reference librarians, circulation librarians (professional qualification not required), children's librarian, school librarians, college and univeristy librarians. The principle purpose of the librarian according to the film is "the improvement of the service to the people in the community".

Why is it that old black and white footage, however worn and crackly, looks better and more interesting than the slick high definition alternatives we have these days?
