Wright, T. G. _Literary Culture in Early New England, 1620-1730._ New Haven: 1920. (Valuable for its check lists of colonial libraries, suggesting books current in Franklin's formative years. The best treatment of its subject although it neglects the literary and aesthetic theories of the period. To be supplemented by books by C. F. Richardson, W. F. Mitchell, and E. C. Cook.)
Further background studies may be found in _The Cambridge History of English Literature_, Cambridge and New York, 1912-1914, VIII-XI, and _The Cambridge History of American Literature_, New York, 1917, Vol. I.

M. Hays.) Philadelphia: 1908. (This valuable work lists letters to Franklin, letters from Franklin, and miscellaneous letters, with brief notes on the topics discussed in each letter and place of publication in cases where the letters have been published.)
_Books Printed by Benjamin Franklin. Born Jan. 17, 1706._ New York: 1906. (Lists best known imprints; useful although eclipsed by Campbell.)

(Lists of "Collected Works," "Separate Works," and "Contributions to Periodicals" constitute a convenient abridgment of Ford, but the list, "Biographical and Critical," limited to two pages, is at best inadequately suggestive.)
