Codexery is a network of 5,109 deep-reference sites designed to make reliable information easier to explore. Across 14 subject areas and nine languages, its codexes contain 175,047 catalogued entries, covering topics from music, sport and games to architecture, science and culture. Rather than offering brief summaries, Codexery builds structured, browsable references that bring together the people, places, works and details within each subject.

The network’s entries are built from cited sources and checked for accuracy. Each codex includes an audit record showing what was verified and what was flagged; when an error is corrected, the record is updated. Codexery describes this checking process as part of its ongoing repair pipeline, not simply a display of credibility.

Its sites are connected across related subjects, so a reference about a football club can link to material about its league or city. Visitors can browse the full index of live codexes, with entries organized into focused collections such as artist discographies, team histories and music genres.
