Historical information: JOP started working on this project shortly after the first Illustrated Dictionary of Pyrotechnics was published in 1995. They gathered information and worked on what would be an expanded version of the Dictionary, which was intended to be available in about two years. At that time, they envisioned a book around 400 pages. However, the work in publishing the Journal of Pyrotechnics did not allow much time to work on the new dictionary. About 7 years ago, they started serious work on the current book. Along the way, they sought help, at various levels, from more than 100 people, who contributed written entries, sketches for illustrations and photographs. Although they spent most of the past two years working almost full time editing and finalizing the text, it seems like there is always more that could be done. As part of the technical editing process, each entry was assigned to one of 14 subject areas and then at least three technical editors, with solid expertise in one of those subject areas, reviewed each of the entries associated with that subject area. This was followed by copy editing by multiple authors addressing format and other minor text related issues.
