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.
