"Author's Note": In May 1989, this article was published in "Livelong Learning," the monthly practitioner journal of the American Association for Adult and Continuing Education (Vol. 12, No. 7, pp. 13-17). Now viewed as a period reference article, it presents the relationship of adult and continuing education (ACE) and human resource development (HRD) in the late 1980s, providing both a description of the differences between ACE and HRD and the conceptual and programmatic reasons for these differences. When asked if it could be published again, I first thought of updating some of the data, particularly the ACE and HRD productivity. I didn't for two reasons. First, it would no longer be a period piece, where you could compare the ACE and HRD productivity with 25 year old data. Second, and more important, the purpose of the article was to emphasize how and why ACE and HRD would benefit from working together. Now, some 25 year later it is my observation that little has changed. The relationship between ACE and HRD is still about the same--they remain competitors that still don't talk and work with each other. [Reprinted with the permission of the author and publisher.
