Fen66 is a catalogued web directory — an archive of active websites classified across twenty-two sections. The collection was assembled to provide a navigable index of the open web, with each entry reviewed and filed individually before accession. The archive operates on a simple principle: record what is active online, organise it into a workable classification scheme, and make the record available to whoever finds it useful. There is no editorial agenda behind the selections; the holdings reflect what has been submitted and verified as operational. Entries in the Fen66 archive span commerce, education, health, travel, technology, legal services, and much more. The general holdings section alone carries nearly two hundred catalogued domains, reflecting the variety of online activity that falls outside any single specialist classification. The archive accepts new submissions continuously. Sites submitted via the accession form are reviewed for basic operational status before being added to the relevant section. This process keeps the collection current and maintains its usefulness as a practical reference. Fen66 is free to browse and free to submit to. The intention behind the archive is to provide a structured, impartial index of the web for those who find such a resource useful.
