This is a difficult book to review because it has a clear objective, but will appeal to a potentially large additional readership for many different reasons. It is a work of scholarship and has been almost a lifetime’s endeavour by the authors, continuing on into their retirement. It follows on from Volume One, covering M to Z. It is a hefty volume and the cover price is not unreasonable for such a work. Some may argue that it is a very competitive price for a book of this type and quality. Strongly recommended.
