Sentinel5

Sentinel5 is a web directory maintained in the tradition of the field notebook — a methodical, categorised log of websites across twenty-two subject sections. It currently holds 828 entries submitted and reviewed for inclusion in the record.

Yes. Submission is open to any site that fits within one of the twenty-two sections of the directory. Review and listing are provided at no cost, and there is no paid placement or premium tier.

Use the submission form linked at the top of each page. Select the section that best fits your site, provide a title and brief description, and submit. The entry will be reviewed before being added to the field record.

Sites are organised into twenty-two subject sections, from Medical & Health and Computing & Software to Travel and Legal Practice. Each section has its own page listing all entries logged within it, along with a short set of field notes describing the section.

Review times vary. The directory is maintained on a rolling basis, and submissions are processed in the order they are received. There is no guaranteed turnaround, but most submissions receive a decision within a reasonable period.

Sentinel5 accepts sites that operate in one of its twenty-two subject sections and that represent a genuine web presence. The directory is broad in scope and does not restrict by region, language, or size of operation.

If your site details change after approval, you may resubmit with the corrected information via the submission form. Note in the description that it is an update to an existing entry, and the record will be corrected accordingly.
