Librarianship may be said to be facing an identity crisis. It may also be said that librarianship has been facing an identity crisis since it was proposed as a profession.

This volume will explore the current purpose of librarianship and libraries, how we become "e;Masters of our Domains"e;, develop expertise in various elements of the profession, and how we extend outward into our communities.
