Book excerpt: For over thirty years the Bibliography of British Railway History has been an essential tool for anyone wanting to study the history of rail transport and one of the foundations for the best of recent railway historical research. The continuing output of new publications about railways is such that a substantial supplement is required from time to time to maintain the work's utility. This is the second such supplement. As well as providing addenda to some of the 13,000 entries in the previous volumes, this volume has 6600 new entries.
