Many of the acute and chronic illnesses confronting the clinician are pulmonary, especially if the associated pulmonary manifestations of cardiovascular diseases are included. Mass screening techniques are discovering active disease processes as well as asymptomatic or incipient pulmonary conditions. Although the present classification of pulmonary disease is incomplete, the one adopted in this volume is generally useful. The material in this book, by 20 contributors, is well presented and well illustrated. A list of references is included.
