Looking around there seem to be three main sources of information on the Sword Worlders; the original JTAS article and the GT and MgT sourcebooks. (I'm purposely not including library data references or things like the Spinward Marches Campaign or Beltstrike where there is "merely" background information). Am I missing another source? And, without triggering a lot of discord, what are the differences between the two sourcebooks in terms of content? Thanks!
