This edition is the third under the editorship of Dr. Nelson. It follows the fifth edition by four years and is the first edition on which the name of Mitchell is missing. Previous editions of this book were widely accepted as leaders in the field of Pediatrics. The recent edition lives up to this reputation in every respect. It has been extensively rewritten. How wide the revision has been is partially indicated by the fact that 12 contributors to the fifth edition are missing in this one, while 19 new authors have been added. Thus there are 19 entirely new sections, while practically all of the others have been revised.
Some of the chapters are reorganized. The discussions of the newborn and the premature infant are combined in a single chapter instead of two. Malignant tumors and miscellaneous diseases have been moved to a more logical location toward the end
