I certainly touched a nerve when asking what your title is and what you call your space! Thanks to the many colleagues who responded to these questions. The short answer is overwhelmingly in favor of Librarian/School Librarian and Library, with Library Media Specialist and Teacher Librarian, and Library Media Center/Media Center in distant 2nd place. Included below is a spreadsheet with all the responses so you can see the wide variety of titles and place names used. I've also included shared some of the comments I've received.
One constant remains - Regardless of what AASL has decreed, or the verbiage in our contracts, DESE licenses or signs outside our doors, we continue to have differing opinions among ourselves in the profession about what we and our spaces should be called. This makes me wonder if using titles and place names other than the traditional Librarian/Library helps to clarify or confuse our roles and the services and resources we provide
