WORKS OF REFERENCE.—Our old friend Who's Who (A. and C.
Black, 40s. net) has appeared already in the edition for 1920. It is larger than ever, like the national expenditure, and runs to nearly three thousand pages for ten times as many biographies. To praise it would be superfluous ; it is unique and indispensable. —The Writer.? and Artists' Year Book, 1920 (same publishers, 3s. 6d. net), edited by Miss G. E. Mitton, is a convenient and practical reference-book, now in its thirteenth year.
