This volume comprises the written Memoranda and Oral Evidence prepared by Alfred Marshall at different times for Government Departments and official enquiries. The Controller of H.M. Stationery Office has accorded permission for the reprint of the passages in question from the various Parliamentary Papers, to which more particular reference is made at the commencement of each extract.
Generally speaking, the Memoranda and Minutes of Evidence have been printed in extenso and without modification. A few misprints have been corrected, some passages from the Memoranda repeated in the Minutes of Evidence have been omitted, and a verbal change has been made in accordance with Marshall's known wishes.
This volume contains the whole of Alfred Marshall's contributions to official enquiries on economic questions with the exception of his work on the Labour Commission. Since he was a member of this Commission, and not a witness, it has been impossible in this case to identify or separate his contributions from those of the Commissioners as a whole.
