'Though much has been written on these subjects, by bibliographers and others, and though Mr Bennett is generous in acknowledging the work of others, his is a peculiarly original and fruitful achievement because of the questions he asks and the special knowledge he contributes ... The many long and splendid quotations not only testify to an enviable range of reading, but also positively advance understanding of the problems discussed. In a field where scholarly competence and worthy labours are common enough, this book, itself the product of scholarship and hard work, stands out because it is also the product of a civilized mind.' G. R. Elton, The Listener
