Signal is a web directory organized on the principles of the reference library — systematic, neutral, and built for browsing. Every site in the catalog is assigned to one of 22 subject drawers, recorded by domain, and timestamped on submission. The index currently holds 837 verified entries, spanning commercial services, specialist trade suppliers, healthcare providers, legal practices, and a broad miscellaneous section for resources that resist easy classification.
The catalog exists because useful sites are scattered across the internet with no common reference point. Signal provides that reference point: a single, well-structured directory where a browser can move from one subject drawer to the next without algorithmic interference or promotional ranking. The index is built to be browsed, not gamed.
Submissions are accepted through the Add a Site form available on this directory. Each submission is reviewed before it is assigned a catalog entry and placed in the appropriate subject drawer. The process takes time, but the result is a catalog with consistent indexing standards rather than an open list.
Signal does not rank entries, sell placement, or apply editorial scores. A site cataloged here is recorded because it was submitted and met the basic criteria for inclusion — not because it paid for position or received a promotional endorsement. Every drawer is organized on the same basis.
The directory is maintained as a public reference resource. Whether you are researching a service sector, sourcing a supplier, or simply browsing the range of sites active on the open web, Signal offers a structured starting point built on reference-library principles and maintained for general use.
