Compass78 operates on a straightforward premise: that a well-maintained web directory, organised with the care of a library card catalog, serves browsers better than an unstructured list. Each listing in this index was submitted by a site operator and reviewed before a reference card was created — recording the domain address, a brief description, and the category under which it was filed. The catalog currently holds 827 approved entries distributed across twenty-two subject drawers. These range from specialist sections such as Oral & Dental Practice and Documents & Certification to broader collections like Digital Index, which holds the largest individual drawer with 189 reference cards. Every entry receives the same treatment regardless of the size of the site it represents. Compass78 does not rank, weight, or editorially favour any entry over another. Listings are arranged alphabetically by domain name within each drawer. Patrons browsing for a particular type of service will find the most direct route is to open the relevant subject drawer and work through the available cards. New entries can be filed at no charge through the submission form on this site. Once a submission is received, it enters a brief review queue before the reference card is written and placed in the appropriate drawer. Sites submitted in good faith and meeting the basic quality threshold are generally accepted. The index is maintained on an ongoing basis. Drawers are extended as new entries arrive, and cards that no longer correspond to active web addresses are periodically retired from the collection.
