It has been more than a decade since the Dictionary of Gnosis and Western Esotericism (2005) was released, the flagship volume of what was then a fledgling field with few reliable introductions and reference works. At the time this was a milestone achievement, pulled off by a dedicated editorial team, 147 authors, and taking the better half of a decade to complete.
That is not to say that the result was perfect. Although the Dictionary was selected a Choice Outstanding Academic Title in 2006, a number of criticisms of selection policy, range, and terminology were put forward and discussed in the academic community from the beginning.
