Early American booksellers, libraries, auctioneers and publishers produced (counting two doubtful cases) at least 286 separately printed book catalogues, 1693-1800, 230 of which are in Readex micro-formats. All but seven of 277 extant documents concerning the placement of double entry literature in the colonial and early republican United States have been reviewed thus far. After the identification of fifty-nine pertinent contemporary bookkeeping sources, partial itemized results are reported based on 151 bookseller catalogues and six publisher documents from Boston, Philadelphia, New York and fifteen other localities. Subject to shared limitations noted in closing, a library/auction sequel will extend this advance in bookkeeping bibliography.
