"This publication provides information on over 650 data collections compiled from a wide variety of historical source material. As such, it is an invaluable aid for any computer-using historian undertaking research or teaching. The volume is divided into three parts: an introduction outlining the nature and scope of the project of which the book is a product; an inventory of datafiles generated by historians located principally in the U.K.; a summary of historical datafiles held overseas; and a set of six indexes, providing quick and easy searching of the text." The primary geographical focus is on the United Kingdom, although some of the data files concern other countries.
