In this collection of thirty articles and speeches, Mr. Gross by his own account has attempted to include ""the widest possible range"" of issues and problems facing the journalist and broadcaster today. Actually it is possible to conceive of a wider range in a shorter compass; too much space has been filled with the kind of thing publishers tell graduating classes and editors tell each other at annual dinners. Still, if the volume is viewed as an anthology rather than a comprehensive textbook, it has some definite values -- and the inclusion of several basic ethics codes, together with some of the important commission reports on the subject, does make it useful for students. If, on the one hand, it is hardly proof of its editor's assertion, that ""the Press today is in a state of vibrant awareness of its increased responsibilities,"" there are assuredly enough interesting rewards in these pages to justify the wary reader's perseverance.
