Silkin's publication "Changing Battlefields: The Challenge to the Labour Party" appeared posthumously. His papers were given to the Churchill Archives Centre by his widow in February 1990. These cover his Parliamentary and Ministerial career, as well as his other public interests, such as the Channel Tunnel, the European Economic Community and the dairy industry. There is material of particular interest concerning his relationship with his Constituency Labour Party in Deptford and on the Labour Party Leadership and Deputy Leadership Elections in 1980 and 1981.
