In 1956 Allison and Rogers published A Catalogue of Catholic Books in English Printed Abroad Secretly in England, 1558-1640. Known simply as A & R, it is the standard listing of the clandestine vernacular output of English Catholics during that period. Now, after more than thirty years work, Allison and Rogers have produced a substantially updated, comprehensive catalogue published in two interlocking volumes. Volume One: Works in Languages other than English (published in 1989) describes books which are linked to specific English Catholic writers, including translators and editors, or to various English bodies, and nearly two hundred other publications which concern English Catholic affairs. It is a major reference tool for historians and bibliographers. Volume Two: Works in English with Addenda & Corrigenda to Volume one is an annotated bibliography of Catholic books printed in English. It includes all the 930 items listed in the A & R, except for a handful which, for reasons of consistency, were described in Volume I and it adds a further twenty-five on which information has come to light more recently. The annotations, historical, literary and bibliographical, are very much fuller than those in A & R and include a vast amount of evidence now brought together for the first time. The true authors of many anonymous and pseudonymous books are identified and many books issued with a false imprint, or no imprint at all, are assigned to particular presses. A concordance links the entries with those in A & R to facilitate cross-reference from one to the other, and indexes of titles, printers and publishers, and persons (including foreign authors) mentioned in the text are provided. Volume II concludes with a short list of Addenda and Corrigenda to Volume I.
