I had assistance from, and in some instances visited, the following libraries: Cornell University, Boston Public Library, Boston Athenæum, Harvard College, Philadelphia Public Library, the Library College of Philadelphia, Mercantile Library College, Philadelphia; the Public Library, St. Louis; that of Lennox and Astor, the University of Virginia, the State Library, Richmond, Va., and one or two other Southern libraries. I have written more than one hundred letters to publishers, editors, authors, the descendants of early American Wordsworthians, Professors of Literature, and professed Wordsworthians in Seminaries and Colleges. I have examined, or employed others to examine, the following works for editions of Wordsworth: the _New York Literary World_, _Norton’s Literary Gazette_, _American Publishers’ Circular_, _Publishers’ Weekly_, _Catalogues of Congress Library_, _The Port Folio_, _American Quarterly Review_, _Knickerbocker Magazine_, _New York Quarterly Review_, _American Review_, _North American Review_. And this is but half of my story. Poole’s “Index,” of course, was a great assistance. But I did not rely altogether on him, after I had discovered several mistakes in titles and numbering--mistakes which were confusing in the extreme. I have consulted all other Indexes and Reference Lists that I could procure, and have carefully examined the periodicals in which it was possible that such articles could be found. My greatest light, however, came from responses to personal appeals, to those in the North, South, East, and West of the Country, who enlightened me in particular directions. I needed assistance, not only to discover the articles, but more particularly to secure the articles to read, or to procure proper persons to read the few articles that I could not obtain. When valuable books were sent me, by express, from distant College Libraries, that I might read for myself, I realised the bond there is between Wordsworthians. I cannot begin to speak of the delight that I have had in this work, delight because of the response I have met with, and in opening up unknown and rich veins of criticism. I have learned too, that Wordsworth has many enthusiastic followers in America. I have included in the Bibliography the accounts of visits paid to Wordsworth by certain well-known Americans, a half-dozen poems on Wordsworth, and three or four unpublished Lectures. I am exceedingly grateful to the many who (to my surprise) have answered my questions, and have given me of their valuable time. I am especially indebted to Mr. George P. Philes, of Philadelphia, and also to Mr. F. Saunders of the Astor Library, New York. Dean Murray of Princeton rendered me exceedingly gracious service, and but for Mr. Edwin H. Woodruff of Stanford University, California, I should not have known how or where to begin my investigations.
