Cornerstone17

Cornerstone17 is a curated reference catalogue of websites, organised across twenty-two subject registries. It functions as an index of the open web — a structured, browsable resource maintained by an editorial curatorial process rather than algorithmic ranking.

Yes. Cornerstone17 does not charge a submission fee. Sites are reviewed by the catalogue's curators and, if accepted, filed under the appropriate subject registry at no cost to the submitter.

Each entry is filed under one of twenty-two subject registries, from the Health & Clinical Holdings and the Legal & Advocacy Registry to the Open Acquisitions section for sites that span multiple subject areas. The subject assignment is made by the curatorial team at the time of review.

Use the submission form on the Add Your Site page. Provide your site's URL and select the most relevant subject registry. The curatorial team will review the submission and file accepted entries within a reasonable period.

Cornerstone17 accepts sites whose primary subject corresponds to one of the twenty-two registries in the catalogue. The index covers a broad range of subject areas including health, finance, technology, travel, legal services, and more. Sites are assessed for subject relevance, not traffic or commercial standing.

The Cornerstone17 index currently holds approximately 829 filed entries across its twenty-two subject registries. The Open Acquisitions section alone accounts for nearly 189 entries, reflecting the breadth of subjects covered.

If your site's URL, name, or category has changed since filing, you may resubmit through the standard form. Include a note in the description field explaining the update. The curatorial team will review and amend the record if appropriate.

No. The catalogue is a neutral reference index. Entries are organised by subject and filing date, not ranked by quality, traffic, or commercial relationship. Cornerstone17 does not accept payment for placement or preferential ordering.
