Working in a library for over ten years, I know quite a lot about the environment, although strictly speaking I am not a 'librarian'.
Within the service that is generally used to refer to someone with a qualification, a degree.
The rest of us (and it is mostly women) are support staff, for these great beings.
Recently, posts that would once have only gone to people with degrees have been filled by people without degrees (gasp!) or at least without degrees in Library and Information Studies.
Whether this is a welcome acknowledgement of the changing nature of libraries, and the skills needed to manage them, it is hard to say. It may simply indicate de-skilling of tasks.
