Report acknowledgment

acknowledgments]],

Acknowledgments of technical assistance that contributed to the content of the report are made at an appropriate place in the preface or in the text; however, lengthy acknowledgments are often made in a conditional section titled “Acknowledgments.” This section follows the preface, in which case the preface does not contain acknowledgments. If there is no preface, "Acknowledgments" follows the contents section (or list(s) of figures and tables and foreword).
