Foreword

In keeping with a flexible editorial policy which has permitted the steady improvement of the Digest over the years, changes in the content of this volume have occurred. The “Magnetics Materials” Chapter is no longer part of the Digest. Members of the AIEE sub-committee on Magnetic Materials indicated that they would continue to prepare an annual digest of their specialty but would prefer to publish it independently. Since the Chapter was invariably prepared as the collaborative effort of a group of specialists not affiliated with the Conference on Electrical Insulation, and since the information was to continue to be made available to interested scientists, it was decided that the literature on Magnetic Materials would not be digested here this year.
