The title of the paper as it appears in the sessional programme, ‘Concerning Historical Bibliography,’ is somewhat vague. What I have to say this afternoon chiefly concerns the forthcoming ‘Bibliography of Modern British History,’ which owes its inception to Fellows of the Royal Historical Society. It is not necessary for me to describe the extensive literature published in various countries and at various times on the subject of Historical Bibliography, as retrospects have been the theme of several papers read by me to the.Library Association, some as far back as 1885, when I first submitted to that body ‘Proposals for a Bibliography of National History,’ since approved, amplified, and improved by Mr. Frederic Harrison and by Dr. G. W. Prothero in addresses before this Society.
