Meadow50 is a curator's index of web sites, maintained as a structured register across twenty-two subject sections. The index currently holds 834 catalogued entries, each placed by a curator who assessed the site for a working presence, a clear purpose, and a stable web address. The Meadow50 index is organised around the principle that a well-kept register is more useful than an undifferentiated list. Each section holds only those sites that belong there by subject, and each entry represents a real web operation rather than a placeholder or redirect. The index spans a wide range of web categories: from dental practices and legal firms to gaming platforms, trade contractors, financial-services businesses, and travel operators. The twenty-two sections of the register are designed to be browsed in sequence or consulted directly by section name. Sites listed in the Meadow50 index are those that were active and accessible at the time of cataloguing. The curator does not warrant continued operation of any listed site, but removes entries that are found to have lapsed. Browsers who discover a broken listing are encouraged to report it. Meadow50 accepts new submissions free of charge. Sites submitted for consideration are reviewed before being added to the register. There is no fee for listing, and no obligation for the curator to accept any submission.
