Blizzard has recently released their official Warcraft Encyclopedia. While it is nowhere near as comprehensive as the WoW Wiki, it does seem to be written in-character. Because of this, it is unlikely to contain major spoilers to in-game quests or events. However, this also restricts the scope of the Encyclopedia severely. On the other hand, the Encyclopedia authors do have one major advantage over the more numerous WoW Wiki authors. It is much easier for them to get clarifications to unsolved issues from Chris Metzen or any other Blizzard employees responsible for the lore. WoWWiki staff will have to rely on in-game sources, books, the roleplaying game, interviews or even mere speculation.
