This is the first edition to collect Milton's non-poetic manuscript writings, and the first edition of Milton's Commonplace Book manuscript to provide both the original text and a full translation and commentary. It is an essential resource for any scholar interested in the development of Milton's thought as assisted by or reflected in his reading. This volume is a consummate work of scholarship and a masterly contribution to the Oxford Milton. It provides everything that a narrowly focused Miltonist might wish for, but it also sees these materials as more than fodder for footnotes to Milton's published writings by locating Milton in the broader world of seventeenth-century scholarship, librarianship, and traffic in books...It is well worth adding to personal or institutional libraries.
