New York: May 26, 1869. 2 pages on a bifolium of 8 x 5 inches, approx. 135 words, the bifolium including on page  a printed series of quotations gathered by professional indexer Allibone under the caption title, “Let no Book lack and Alphabetical Index,” touting the value of indices. A trifle dust-soiled, one corner bent; in fine condition. Item #18122
Allibone writes to Sprague to thank him for receipt of “Vol. IX of your great work”—unnamed here but clearly the final volume of Sprague’s Annals of the American Pulpit, this volume published in 1869. Allibone notes, “I was sorry to hear – what I hope will prove incorrect – that you had abandoned the idea of including the Roman Catholics in your Annals,” and makes a referral to pioneering American Catholic historian J. G. Shea. Allibone eventually approaches the reason for his note—he has sent Sprague a copy of his own Alphabetical Index to the New Testament, and asks “if you think it calculated to be useful I would be much gratified by a few words to that effect (with permission to quote them). In my latter letters of the alphabet I have often occasion to refer to your invaluable work.” Allibone is remembered for his biographical index of American and English authors, as well as his indexing work—alluded to here on this handsome and curious indirectly promotional stationery. Small faint later violet ink ownership stamp to the blank lower margin of the second page.
