Quorum12 is a structured web directory organised on the principles of the library card catalog. Each listed resource is filed under a specific subject heading within one of 22 classified sections, making it easier to browse by topic rather than by name or popularity.

Every site in Quorum12 is assigned to exactly one primary subject heading — for example, Healing Arts & Clinical Reference or Applied Sciences & Computing. The subject heading reflects the site's principal purpose. Where a resource touches more than one subject, a cross-reference note appears in the adjacent section.

Yes. Quorum12 does not charge for accession records. Site owners submit a URL and a brief description through the standard filing form; editorial staff review the submission and assign the appropriate subject heading before the record is opened.

Use the Add a Site form accessible from the top navigation. Provide your full URL, a short description of the site's primary subject, and a suggested section heading. Submissions are usually reviewed within a few working days.

Yes. Each submission is checked to confirm the site resolves correctly and that the proposed subject heading is appropriate. Quorum12 may reassign a submission to a more precise heading or decline it if the resource duplicates an existing accession record.

Contact the Quorum12 editorial team with the relevant URL and the correction required. Minor updates — such as a change of description or category — are processed as amendments to the existing accession record rather than as new submissions.

The current catalog holds 833 accession records across 22 subject sections. The collection grows as new submissions pass editorial review; the count shown on the home page is updated each time a new record is opened.

Quorum12 performs periodic checks on filed accession records. If a listed domain is found to be unresolvable, the record is marked inactive and removed from the browsable index. Site owners who migrate to a new domain may submit an amendment to update the existing record.
