We know what we do. We know librarians are highly educated, capable people with information, managerial, technology and instructional skills. It's a demanding, highly skilled and multifaceted job. I far prefer being called a media specialist. Some will argue that it's not what you call yourself that matters, but what you do, what people see you doing, or what people perceive you do.
Titles are meaningless if the service and educational value provided are also meaningless.
I recognize everyone's right to use the title they are most comfortable with. But, unfortunately the perception still exists among some that librarians just take care of books. When considering funding, our state legislators link school-media programs with public libraries. That is a situation that has provided benefits, but does not recognize our different roles and the uniqueness of school-media programs. Worse yet is the persistent negative stereotype in popular literature depicting librarians as stern, plain or frumpy people who are primarily concerned about overdue books.
