First published in 1991. Routledge is an imprint of Taylor & Francis, an informa company.

This volume contains 375 letters by John Stuart Mill, further to the publication of "Earlier Letters" in 1962 and "Later Letters" in 1972. Although it covers a vast range of topics, the collection focuses on three groups: a series of letters to Henry Cole, dealing amongst other things with the disposition of the "London and Westminster Review"; the full versions of letters to Theodor Gomperz, Mill's leading German disciple and translator, which had been thought destroyed; and recently-found internal correspondence in the Examiners office of the East India Company, which sheds new light on Mill's career. The editors' introduction places the letters in context, gives detail about the three special groups, and outlines the history of the collection. The letters are presented in full scholarly form, with notes giving information about the texts and their provenance, and also historical and biographical information.
