Cadence3 is a freely accessible web directory that maintains a catalogued register of sites across 22 subject areas. The project was conceived on the principle that a well-organised index of the web — methodical, consistently described, and open to new accessions — serves a different purpose from search engines and social aggregators. Where those systems surface results by popularity or algorithmic inference, Cadence3 offers a stable, browsable record of what is filed where. The directory currently holds 835 approved entries. Each accession carries a domain name, a descriptive title, a category assignment, and a short account of the resource. The 22 sections range from the heavily populated — Gaming & Wagering Ledgers holds over a hundred entries — to smaller specialist areas such as Official Documents & Licensing Files and Property Records & Estate Registers, which remain open for new submissions. Submitting a site to Cadence3 is straightforward and free. Site owners complete a short intake form supplying a URL, a title, and a preferred category. Each submission is reviewed by the archivist before being added to the permanent register. There is no charge for a listing, and no premium placement is offered; every approved entry receives equal treatment in the catalogue. Cadence3 does not claim to be a comprehensive index of the entire web. It is a curated and actively maintained register: one that grows by deliberate accession rather than automated crawl. The archivist welcomes sites of genuine quality and relevance, and the open stacks section accommodates resources that do not fit neatly into the defined subject headings. The directory is designed for human browsing. Each section page presents its entries in a consistent format, and the site map gives a clear picture of the full collection. Cadence3 is maintained as a long-term reference resource, and entries that remain live and relevant are kept in the register indefinitely.
