"This sixth revised edition is a cooperative effort of the BPS and Pariyatti. In this edition the abbreviation scheme and reference systems have been modernised. Moreover, some of the “source notes”—made in an age when digital search tools were not available, and originally located in an appendix—have been revised by me in order to accurately reflect the first occurrences of terms and to avoid duplication of statements already found in the entries. The British spelling of words has been retained."
