Recorded between 1710 and 1777, the Bowyer ledgers offer a vast store of new information concerning authorship, book production, and distribution in eighteenth-century London. More than five-thousand works by one thousand authors were commissioned during that time. The ledgers record what happened as the text moved through the printing-house, noting such particulars as paper, types, format, corrections, and number printed. This edition of the Bowyer ledgers presents the records themselves in photofacsimile on microfiche, accompanied by a volume of editorial apparatus, which includes an essay on the nature and function of the ledgers, and a chronological checklist of works printed by the Bowyers, an index of authors and titles, and a topical index of equipment, materials, and processes.
