Donald Mack, an American living in England and a member of the Society of Technical Analysts (STA), became interested in TA in the mid-1960s. In the late 1970s, he established the only bookstore in the U.S. that dealt exclusively in stock and commodity books and built a personal collection of around 5,500 titles. A few of these forgotten classics were republished as a series, edited by Donald Mack and published by FT Pearson.
