It is an ongoing issue in the world of librarians about how touchy MLIS holders should get when non-MLIS holders get called “Librarian”.
When it comes to the public, the people that come in and use libraries, I believe the vast majority don’t care about the particular educational achievements of the person they are getting help from, they just want them to provide the service they need.
In this article from the North Country Times in California:
the writer and the people quoted in the article use the terms library technician and librarian interchangebly. All the parents care about is that they may have to share with other schools the library technician they admire and beleive helps their children. To them, a person who provides all these services at such a high level is a “librarian” in their eyes.
While I certainly beleive in the general concepts behind the occupational divisons between library technicians and librarians, I think anyone who gets hung-up on how the public uses the title “librarian” needs to find other things to worry about.
