This project is being conducted in partnership with the Special Collections division of the Library of Somerville College, Oxford, which houses the library of John Stuart Mill and his father, James Mill. We are working together to create a multi-faceted open access digital resource showcasing the manuscript marginalia written in texts by both J. S. Mill and his father, enabling researchers and students to read these alongside scholarly writing about these materials. The website will also furnish researchers with a suite of supporting materials giving context to the marginalia, and more broadly the rest of Mill’s holdings.
