A few years ago HMSO changed the size of this publication from Royal Octavo to A4. In the interests of those subscribers who prefer the previous size we have continued to provide a version in Royal Octavo.
Volumes vary in number from year to year.
Parts are sent to subscribers as they are printed, and invoiced with delivery of the final text part. When this is completed with tables, bound volumes are available. This new volume in the familiar red buckram is the fourth in this unique and invaluable series of reference books which commenced publication in 1951. All of these are helpfully cross-referenced. The cases are indexed alphabetically and by subject matter for ease of reference.
