Extra-Help Librarians are commonly known as substitute librarians in public and school libraries and adjunct librarians in academic libraries. Even though each institution has it's own mission and it's patrons have their own characteristics, the Extra-Help Librarian category has similarities among locations. Therefore, this book focuses on their professional profile and work issues in these library settings. It is geared to anyone interested in pursuing a Library Science degree, to students and recent graduates and to professors in this field. In addition, retired librarians and those between jobs or re-entering the job market could benefit from the book's content.
