Signal87A Web Herbarium

Signal87 is a web directory that indexes websites across 22 defined sectors. It is maintained in the tradition of a geographic gazetteer: each entry is a recorded station, catalogued by field and held in the index for reference. The directory currently logs 830 approved sites.

Yes. Signal87 accepts submissions at no cost. Any site owner may enter their URL, select the appropriate sector, and submit a brief description for review. Approved entries are added to the index without charge and remain listed without any renewal fee.

The directory is divided into 22 sectors, each covering a distinct field of activity — from financial services and medical providers to travel, computing, and general interest. Within each sector, entries are listed in a consistent format regardless of the size or commercial standing of the operator.

Submissions are reviewed on a rolling basis. There is no fixed turnaround; most submissions receive a decision within a reasonable period. Once approved, a site is entered into the index and becomes visible in its sector.

To update an existing entry, use the contact method on the About page. Provide the current URL, the correction required, and a brief explanation. An editor will review the request and update the record accordingly.

Any website owner or administrator may submit a site for inclusion in Signal87. The directory accepts submissions from operators in any country and in any language, provided the site represents a genuine business, service, or resource within one of the 22 defined sectors.

Yes. Signal87 indexes sites from across the world. Country of origin is not a factor in the review process. Operators in any territory are welcome to submit their station for inclusion in the index.
