FAQ

What is Compendium3?

Compendium3 is a curator's index of web resources, organised into 22 subject sections. It holds 829 catalogued entries, each admitted after review by the curator. The index is maintained as a structured reference to the open web — a catalog of what exists, arranged by subject.

Is it free to list my site?

Yes. Compendium3 does not charge for listings. Submit your site using the form, and if it is approved, it will be added to the relevant subject section at no cost.

How are sites organised in the index?

Compendium3 organises entries into 22 subject sections, from automotive and dental practice to leisure travel and general reference. Each section holds sites whose primary subject corresponds to that category. Sites that span multiple fields are placed in General Reference.

How do I submit a site?

Use the submission form on the relevant subject section page or the main submission page. Enter your site URL and select the most appropriate category. The curator will review your submission and, if approved, add it to the index.

How long does review take?

The curator reviews submissions regularly. Most entries receive a decision within a few days. You do not need to register or provide contact details to submit; check the catalog to confirm whether your entry has been admitted.

What types of sites are accepted?

Compendium3 accepts sites across all 22 subject sections, provided they are accessible, their subject corresponds to the selected section, and they are not duplicates of existing entries. There is no restriction on site size, country of origin, or commercial status.

Can I edit or remove my listing?

To request an amendment or removal, use the submission form and include your site URL and a brief note explaining the request. The curator reviews all such requests and will act on those that can be verified.
