Almanac39 is a web directory maintained in the manner of a reference almanac: each entry is examined, classified, and assigned its proper place within the catalogue before publication. The directory currently holds 834 sites organised across 22 sections, ranging from legal chambers and medical practitioners to gaming establishments, computing firms, and grand tour operators. The archivist's aim is a directory that earns its consultation. Too many indexes of the web accumulate entries without discrimination; Almanac39 proceeds differently, admitting only those sites that represent an identifiable trade or service and meet a basic standard of presentation. The result is a leaner catalogue than most, but one in which the entries are more reliably useful. Section headings in this directory follow the conventions of the reference almanac: formal, precise, and arranged to make retrieval straightforward. A reader seeking dental care will find it under Dental Practice & Oral Care; one seeking a solicitor will look under Legal Chambers & Counsel at Law. The taxonomy reflects how trades are actually organised, not how search engines happen to cluster them. New entries are accepted by submission and reviewed before inscription. The process takes time, as the archivist examines each submitted site individually. Submissions that meet the catalogue's criteria are admitted without charge; those that do not are declined with a brief note of reason. There is no mechanism for purchasing placement in this directory. Almanac39 is updated on a rolling basis as new submissions are received and assessed. The catalogue does not aim for comprehensiveness — that is the ambition of the search engine, not the almanac — but for considered coverage of the principal fields of contemporary commerce and service.
