I acknowledge with gratitude my indebtedness to all those who contributed material to this number of the annual Review. Due to the diversity of the material incorporated herein and the vastness of the subject, the possibility of a few editorial inaccuracies cannot be ruled out, for them I must apologize. However, in regard to factual information and the interpretation of data the responsibility rests with the contributing parties. I am thankful to my colleagues and staff-members for the assistance rendered by them in bringing out the Review.

I cannot finish this preface without a personal note. I started this Review in 1954 almost as an experimental measure, explaining ill the Preface thereof its scope. Thereafter the arrangement of the items appearing in the subsequent numbers has been improved to the best of my ability and the subject-matter has become more comprehensive. At present hardly any publication on Indian archaeology can do without referring to some matter or the other appearing in the Review. This shows that the experiment has been a success. Unfortunately, due to circumstances beyond our control there has been of late some time-lag between the period covered by each number and the date of its publication. I am shortly retiring from my present position, so that this will be the last number edited by me, but I earnestly hope that under my successor, Shri B.B. Lal, who will be the next editor, the arrears will be cleared up and the Review will make itself all the more useful to Indian archaeology.
