If I remember right, the order is roughly the same as the order they are usually listed in the credits of each product - although depending on the product the order is sometimes different. You can also see that I tried to group them into categories, so that all of the variations remain close to each other.
A few of the credits were so similar that I merged them, with a slash separating the different variations of the job title. It might be sensible to further merge some of these, or even to establish overall categories to which these titles can be assigned as sub-categories. That would facilitate searching a bit better. For example, Artist, Illustrator, Cover Artist, and so on could all be sub-categories of "Artist". Since some titles include two areas (e.g. Production & Design, Developer & Editor), we would need to be able to add one job title to multiple categories, but I don't think that would cause any problems.
Note that I have not researched magazine credits (although most if not all article credits are already provided for in this list), nor products outside the Mystara range. We will probably want to expand the lists to include other AD&D products for reference purposes, including 1st, 2nd, 3rd and eventually 4th editions.
Also note that "Author Types" deals only with job titles; all other aspects are covered in different tables.
