Talk:Elminster's Guide to Magic

Is this a legitimate book or is it a fan-work or 3rd-party piece? I can't find it on the WotC site, it's PDF-only, the cover is awful, lacks official branding, and doesn't follow the layout of Volo's Guide to Monsters or Xanathar's Guide to Everything, and its publisher is Dungeon Master's Guild, not Wizards of the Coast. I think it might not be canon. — BadCatMan (talk) 02:00, September 20, 2017 (UTC)
