A list of the English-language Shadowrun books, with their SKU numbers. Sourcebooks Four digit numbers were published by FASA; sometimes prefixed by "FAS" Five digit numbers were published by: FanPro: 106××, 250××, and 2600×; sometimes prefixed with "FPR" Catalyst: 26×××, with the third digit specifying the book type; 0 for core rulebooks, 1 for core supplements, 2 for settings (locations), 3 for general sourcebooks, 4 for Adventure, 6 for Rules Supplement, 7 for premium, 8 for fiction and 9 for misc; sometimes prefixed with "CAT", "CGL" or "CYT" Core rulebooks and supplements are primarily composed of rules, and tend to be replaced quickly when a new edition of the game is released. They can be difficult to use with other editions. Second and Third edition were pretty similar, while the Fourth and 20th Anniversary editions were quite different than the first three. Fifth edition built on the Fourth/20th anniversary, while Sixth edition again makes a number of changes to the core rules. Shadowrun Anarchy is almost a different system entirely. Sourcebooks are a mix of rules and setting. As such, they contain setting information applicable to any edition of the game, and statistics that may need a little updating. Foreign language editions of sourcebooks often contain additional content relating to local variants on the topic in question. Sometimes even whole original books have been published concentrating solely on providing local source material. Magazines There were two short lived, FASA approved, paper magazines for Shadowrun. The first—KA•GE—was published by The Shadowrun Network, with thirteen issues. The second—Shadowland—was published by Sword of the Knight Publications, with seven issues. † If there was no in game date on the cover, the most recent date-stamp within the issue is listed. † The most recent date-stamp within the issue. Novels and other fiction FASA published the original trade paperback through Contemporary Books. All subsequent novels were published by ROC, 40 with FASA (1990–2001), and six with WizKids (circa 2006). When the FASA era novels were re-released in 2003 the ISBNs were updated to include FASA's four digit SKU (ISBN ×-×××-×FFFF-×), prior to this the FASA SKU and ISBN were generally unrelated.
