The first printing of this book came in 1942 during World War 2.  There was a built-in demand for "how to interview" instruction, for social workers, schools & colleges, research workers, counselors, the professions, volunteer groups, etc.  This book is the 22nd edition 1962 of that humble beginning....and there were more...ending up with a 340 page textbook in 1995---This edition, in 123 pages, is good for someone who wants a good outline of the essentials of "Interviewing". ---
