Codex4 is a web directory that catalogues sites across 22 subject fields. Entries are observed and logged as field specimens in the relevant section. The current record holds 831 entries.
Entries are filed by subject field. Each of the 22 sections covers a distinct area of web activity — from healthcare and legal practices to travel routes and chance games. Sites within a section are listed without ranking.
Use the submission form accessible from the main navigation. Provide the site address and select the subject section that best describes its content. Each submission is reviewed before an entry is confirmed.
Review times vary. Submissions are assessed periodically and added to the record when they meet the criteria for listing. Codex4 does not correspond with submitters individually about the outcome of a review.
Yes. Each site is treated as a separate field specimen and reviewed independently. Submit each site using the submission form. There is no limit on the number of sites a single operator may propose.
No. Section sizes vary considerably. The chance-games section holds 117 entries, the largest field in the directory. The property section holds 5, the smallest. These differences reflect observed specimen density, not editorial priority.
