+ Add your stopColophon42 is a web gazetteer—a structured catalogue of active internet addresses organised by subject. It is modelled on the printed gazetteers and regional atlases that preceded the digital era, adapted for the task of mapping online destinations across 22 subject sections.
Yes. Submission of a web address to the Colophon42 catalogue is free of charge. Any operator of an active and publicly accessible website may submit their address for consideration using the form on this site.
The gazetteer is divided into 22 subject sections, each corresponding to a broad domain of human activity—from Wagers & Parlours and Medicine & Remedies to Passages & Waystations and Systems & Programs. Each submitted address is assigned to the section that best fits its primary subject matter.
Use the submission form available on this site. Provide your web address and select the most appropriate section from the list. The editorial team will review your submission and add it to the catalogue if it meets the basic criteria: an active, publicly accessible address with a defined subject area.
Reviews are processed in order of receipt. Most submissions are assessed within a few days. You do not need to create an account or follow up; if your address is approved, it will appear in the relevant section of the catalogue automatically.
If your site's address, title, or description has changed, you may submit a correction via the submission form, noting that the entry already exists. The editorial team will review and update the catalogue entry as appropriate.
The gazetteer does not include addresses that are inactive, return error responses, or cannot be clearly assigned to one of the 22 subject sections. Sites that are under construction or have not yet launched publicly are deferred until they are ready to receive visitors.
Colophon42 is a reference gazetteer of the open web, cataloguing 832 approved web addresses across 22 subject sections. The directory is organised in the manner of a regional atlas: each section corresponds to a domain of human activity, from Wagers & Parlours and Medicine & Remedies to Systems & Programs and Passages & Waystations. Entries are recorded without editorial recommendation; the gazetteer's purpose is description, not prescription. New addresses may be submitted by their owners using the submission form; each submission is reviewed before inclusion. The catalogue is updated as new entries are approved and is intended as a practical cross-reference for researchers, browsers, and anyone mapping the current shape of the world wide web.
