This is a listing of all the "official books" I have pulled rules from over the years.
I maintain all of these in paper format and most of them are in digital formats as well.
As I reformat the digital versions they will be added here in a way that respects the copyright owners. Some information taken from these books appears on this site and is used here to provide existing players ease of access to the information. This is limited to fair use of a few tables or charts. In no way is any infringement on the various original copyright holders intended. Original paper and digital copies of all works referenced are maintained outside of this site.
