WORK.S OF REFERENCE.—Who's Who in America, .7920-21, edited by Mr.

A. N. Marquis (Stanley Paul, 45s. net), is the eleventh issue of this comprehensive and well-edited book of reference, which, we are told, contains 23,443 biographies. When it was printed, Mr. Harding was still a Senator and had not been nominated for the Presidency. If the book is thus a few months behind the times, it is extremely useful, for we need to know something about many public men in America.
