The field of Adult and Continuing Education (ACE) has long been influential beyond its already porous borders, and continues to be a source of important ideas, inspiration, and innovative practices for those in disciplines such as educational administration, social work, nursing, and counseling. Recognizing this, the American Association for Adult and Continuing Education commissioned the editors to create this compendium, which provides an invaluable resource to readers already established in the field, those entering the field, and to myriad neighbors of the field as well.

The final volume, on Inquiry and Influences, examines the context, trends, and methods of research and evaluation in the field’s many domains. Wide-ranging inquiry has always been a hallmark of ACE, and only continues to grow along with the recognition of the importance of adult learning for learners and for the society as a whole.
