The online database is refreshed fortnightly. The data load takes place overnight from late afternoon on Wednesday to early Thursday morning. Whilst the data loading is taking place, certain functions of the site such as the search facilities may not operate correctly.
The master HER database is being updated on a daily basis. New sites are being added, new photographs and reports linked to records and corrections and updates are being made to existing records. The New Additions section of the website features new site information and fieldwork reports added to the HER within the last month.
