AMERICAN MEN OF LETTERS

Biographies of our most eminent American Authors, written by men who are themselves prominent in the field of letters. Each volume, with portrait, 16mo, gilt top.

The writers of these biographies are themselves Americans, generally familiar with the surroundings in which their subjects lived and the conditions under which their work was done. Hence the volumes are peculiar for the rare combination of critical judgment with sympathetic understanding. Collectively, the series offers a biographical history of American Literature.
