The Casebooks Project is a digital product offering a tool for searching and reading the medical records of the astrologers Simon Forman and Richard Napier. It covers 1596-1634. The project is ongoing: 48,500 cases are now live. When complete, it will contain 80,000 cases and images of the manuscripts. Our editors transcribe the formulaic material at the beginning of each entry, and categorise and tag it using historically sensitive analytic categories. Full transcriptions of the casebooks are not provided, but other information in the records, including information about individuals and their associates, is tagged and can be searched.
