This volume contains important material not found in the original edition: an index to printers and publishers. It also contains addenda and corrigenda to the 1926 edition, and to the first two volumes of the second edition. The new Printers' and Publishers' Index has headnotes 1) giving each individual's dates of activity, 2) supplementing and in many cases correcting information in the Bibliographical Society's Dictionaries of Printers, and 3) listing addresses of British publishers in far more complete and accurate detail than available previously. There is a second index, entirely new, of places of printing other than London, including fictitious places. The addenda and corrigenda are cumulative, incorporating and occasionally revising those which appeared in the first two volumes of the revision. Information first appearing in the present volume is distinguished by a bullet and revisions of previous addenda by a second bullet so that users of STC may more easily annotate their copies of the first two volumes.
Alfred William Pollard (14 August 1859 – 8 March 1944) was an English bibliographer, widely credited for bringing a higher level of scholarly rigour to the study of Shakespearean texts.
Pollard was educated at King's College School in London and St John's College at the University of Oxford. He joined the staff of the British Museum in 1883, as assistant in the Department of Printed Books; he was promoted to Assistant Keeper in 1909, and Keeper in 1919. In the latter year, Pollard was appointed Professor of English Bibliography at the University of London. He was Honorary Secretary of the Bibliographical Society from 1893 to 1934 and edited the Society's journal The Library for thirty years (1903–34). He received the Society's Gold Medal in 1929.
Pollard wrote widely on a range of subjects in English literature throughout his career, and collaborated with various scholars in specialized studies; he edited Thomas Malory's Le Morte d'Arthur, and a collection of Fifteenth Century Poetry and Prose. With Gilbert Richard Redgrave, he edited the STC, or A short-title catalogue of books printed in England, Scotland, & Ireland and of English books printed abroad, 1475–1640 (1926).[2] He was a longtime friend of the poet A. E. Housman, and a close colleague of the prominent Shakespeare scholars Edmund Kerchever Chambers and R. B. McKerrow.
