HE object of this work is to bring together the information available T respecting the men and women who printed and sold books during the twenty-seven years from 1641 to 1667. It is an attempt to fill the gap between the Stationers' Registers and the Term Catalogues so ably edited by Mr. Edward Arber. The information consists of imprints showing the various places in which such booksellers and printers carried on their business, such biographical details as could be gleaned from various printed and manuscript sources, and an indication of the character of the trade carried on by each bookseller. As a further help to the bibliographer, I have included a notice of all publishers' lists that I have met with. It was my original intention to have given an indication of the work of each printing house, but I soon found that this 'was impossible. Such printing houses as those of the Fletchers, Roycroft, or Warren are in themselves a study, and any attempt to generalize was worse than useless.
