The WordPress Codex was founded to revitalize the collaborative documentation effort for WordPress which had begun to wane on the previous documentation wiki. The goal of the Codex is to be an encyclopedia of WordPress knowledge. It takes its name from codex (latin for book), which was the first invented form of paged volume we recognize as a book, immediately succeeding the scroll as means to record writing.
Part of the reason for the decline of the previous wiki was the user-unfriendliness of the wiki tool we used. We've chosen a new tool for Codex called MediaWiki — developed by the Wikipedia team — which we think will greatly enhance the user experience.
The second issue with the previous wiki was in the organization of its contents: it developed without a structure, making it extremely difficult for users to find information. We hope to alleviate this in the WordPress Codex by implementing guidelines for its organization and by keeping a devoted group of moderators to enforce these guidelines.
