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 to be published in two interlocking volumes. This first volume 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. ''The one thing that has characterised the two editors in everything they have done is their careful and painstaking scholarship, and that is evident throughout this work...this monument will stand for a long time and serve students of the history, religion, and literature of early modern Europe for many years to come'' The Catholic Historical Review ''a remarkable achievement...If there is such a thing as an absolute bibliography, then this is it'' TLS A.F. Allison had special responsibility for early printed books at the British Museum Library, while D.M. Rogers was head of Special Collections in the Department of Printed Books at the Bodleian Library. Both have written widely and together founded, in 1951, the periodical ''Biographical Studies'', later re-named ''Recausant History''.
