Calling All Professionals

One of my former library directors once said that librarianship is not a job; it is a profession.  What makes a professional?  What makes something rise above the mere label of "job?"  Perhaps it is the advanced education that we pursue.  Perhaps it is the skills that we have honed through our preparation.  Perhaps it is the body of knowledge that we have mastered.  Perhaps,it is an understanding of practices that we know how to use. Perhaps it is a sense of higher calling.  Perhaps it is our dreams and ambitions.  Perhaps it is our passion.  Once a librarian, always a librarian.  I've had jobs before, but I am a librarian; I am a professional.
