Compendium25 is a free web directory that catalogs 830 reviewed sites across 22 subject sections. The project takes its name from the idea of the compendium — a concise but thorough collection of recorded knowledge — applied to the task of indexing active businesses and services on the open web.
The directory is organized into twenty-two sections covering commercial and professional sectors: from health services and legal practices to gaming platforms, technology firms, and travel operators. Each section is a distinct chapter in the field notes, holding entries that have been logged from live submissions and verified as active domains.
Every entry in Compendium25 follows the same field format: a domain, a business name, and a brief description supplied by the site's owner at the time of submission. Compendium25 does not editorialize or rank these entries; the catalogue is a factual record, not a recommendation service.
Site owners across all twenty-two sections may submit their domain free of charge. Submitted entries are reviewed against a basic set of criteria — the site must be live, the domain must not already appear in the catalogue, and the entry must be assigned to an appropriate section. Approved submissions are added to the relevant section of the field notes.
Compendium25 is part of an open web directory network and is maintained on an ongoing basis as new submissions are received and reviewed. The field notes grow with each approved entry added to the catalogue.
