About Cornerstone24
Cornerstone24 is a web directory built on the model of the field notebook — a methodical, openly accessible record of websites catalogued by category. The directory was assembled from operator submissions and is maintained as a living index of web presences across 22 sections.
The name reflects the approach: a cornerstone is a reference point, a fixed mark from which other measurements are taken. Cornerstone24 aims to be that kind of reference — stable, consistent, and navigable — rather than a trending feed or a paid placement board.
Entries are reviewed before publication. Sites are listed by the domain submitted by the operator, grouped into the section that best fits their primary activity. Where a site spans multiple categories, it is placed in the section most relevant to its main offering.
The 22 sections cover a broad cross-section of commercial and informational activity: from dental practitioners and legal counsel to gaming platforms, travel operators, and industrial suppliers. The Sundry Entries section captures submitted sites that did not fit neatly into a named category.
Adding a site to Cornerstone24 is free. The submission form accepts a URL, a short title, and a category selection. Once submitted, entries are reviewed and, if approved, added to the relevant section of the catalogue. The directory does not charge for listing, and placement is not influenced by commercial arrangement.
Cornerstone24 is one entry in a broader network of independently maintained web directories. Each directory in the network covers the same inventory under a distinct brand and design, allowing the catalogue to be consulted from multiple access points across the web.
