Book excerpt: Analysis of the great demand for this work over a number of years has revealed that conference participants and interpreters, for whom the manual was primarily intended, are by no means alone in appreciating the usefulness and reliability of this unique publication. Whilst the editor has taken account of a small number of linguistic refinements and preferences in recent conference usage and has carefully reviewed the original material, he has seen no reason to enlarge the scope or alter the format of the previous edition - both these features of an essentially concise handbook having clearly met the practical requirements of its many users. For this edition the number of languages has been increased to include Hungarian.
