The Exploded Library has written more on the librarian shortage debate for the The Australian Library and Information Association. Like the author, I agree that the article addresses a global issue.
The library directors and leaders of the future don't just appear, they hired into entry level positions, and then mentored, promoted and groomed for management. Are you doing your bit to ensure that this happens?
My thoughts? Both library staff and working librarians need to do everything they can, including using any and all staff training opportunities, to stay current and viable in the library work-place.
