Instead what it means is what most people think of when they think of a book for a table-top role-playing game. It's a book that contains rules as well as lists of items, magic spells, monsters the players might encounter, devices they might find and so on. </p><p>These types of books contain information on a lot of fictional devices, concepts and other minutiae of the fictional setting the game takes place in. </p><p>It should be noted that books like the Star Wars Technical Manuals are a sourcebook just as much as books like <a href="/wiki/Dungeons_and_Dragons" class="mw-redirect" title="Dungeons and Dragons">Dungeons and Dragons</a>' Monstrous Compendium or Toon's Acme Catalog. It need not be a pen-and-paper RPG that's the subject: the important distinction is that the work is mostly a list of fictional items from an in-universe perspective </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Why_are_"sourcebooks"_a_problem?" data-mw-thread-id="h-Why_are_"sourcebooks"_a_problem?"><span id="Why_are_.22sourcebooks.22_a_problem.3F"></span><span data-mw-comment-start="" id="h-Why_are_"sourcebooks"_a_problem?"></span>Why are "sourcebooks" a problem?<span data-mw-comment-end="h-Why_are_"sourcebooks"_a_problem?"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Sources_must_be_out-of-universe&action=edit&section=2" title="Edit section: Why are "sourcebooks" a problem?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Because these types of books exist, it may appear at first that an article on a very minor item has a staggering number of citations and references. Sourcebooks rapidly can create an echo chamber of sorts, re-reporting and re-releasing the same information over and over without actually saying anything significant at all. </p><p>Take as an example a common pistol from <a href="/wiki/Shadowrun" title="Shadowrun">Shadowrun</a>: the Ares Predator. It appeared first in the first edition core rulebook. It was also mentioned in that edition's gun compilation, the Street Samurai Catalog. As editions changed it was in the second edition of both of those books. But come third edition the Street Samurai Catalog was replaced by the Cannon Companion, that's book #3 that can be cited. Then in fourth edition the title of the gun sourcebook changed once again. That's a total of 6 books none of which say a single thing about it other than what it is and some in-universe information about its popularity with mercenaries in the setting and its reputation for reliability. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="The_solution" data-mw-thread-id="h-The_solution"><span data-mw-comment-start="" id="h-The_solution"></span>The solution<span data-mw-comment-end="h-The_solution"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Sources_must_be_out-of-universe&action=edit&section=3" title="Edit section: The solution"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Because of this effect it is vitally important to make sure that the sources say something other than purely in-universe information. A short description of what an item does is important context for an encyclopedic article, but (as <a href="/wiki/Wikipedia:WAF" class="mw-redirect" title="Wikipedia:WAF">WP:WAF</a> says) the primary frame of reference at all times should be the real world. <a href="/wiki/Wikipedia:NOT" class="mw-redirect" title="Wikipedia:NOT">WP:NOT</a> also states that information presented in an encyclopedic article should not be primarily of use to someone playing the game (and by extension reading the series, etc.). </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="an_example" data-mw-thread-id="h-an_example"><span data-mw-comment-start="" id="h-an_example"></span>an example<span data-mw-comment-end="h-an_example"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Sources_must_be_out-of-universe&action=edit&section=4" title="Edit section: an example"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The Corellian Engineering YT-1300 Light Freighter from Star Wars is unimportant as a group of ships, but the <a href="/wiki/Millennium_Falcon" title="Millennium Falcon">Millennium Falcon</a> probably IS notable, even though it's a YT-1300.
