Landmark64 is a running ledger of active web presences, organised into 22 subject accounts and maintained as a reference index for the open web. The directory holds 830 entries drawn from a wide range of sectors and services, each filed under the account heading that best describes its primary activity. The directory operates on a straightforward classification model. Every listed site is assigned to one of 22 subject accounts — from Gambling, Gaming & Casinos and Healthcare & Medical Facilities to IT, Software & Technology and Tourism, Travel & Transport. Within each account, entries are recorded in order of submission date, giving a clear running log of activity in that sector. Landmark64 accepts submissions from any legitimate web presence. Sites are reviewed before being entered into the index. The submission process is open and free of charge. Operators wishing to have their site recorded should use the submission form and select the account heading that most accurately reflects their primary service. The directory is maintained as a neutral reference resource. It does not rank, endorse, or evaluate the quality of listed sites. Its purpose is to provide a structured, browsable index of active web addresses organised for ease of reference by subject category. Each account page in Landmark64 displays the recorded entries for that subject, along with a short description of the account scope and a survey of what the category covers. The home page shows recently filed entries across all 22 accounts.
