From the Preface: The primary aims of this book are to highlight the main aspects of the preparator's work, describe as many techniques as practical, and guide the reader to the relevant literature, from which more information can be gained. To prepare a book of this kind, one must draw heavily on the published and unpublished research of many other workers, present and past. As it is not possible to describe every technique which may be practiced in a biological museum, lists of useful publications are provided at the end of the chapters. In most cases when animal preparation is discussed, the grouping is not governed by any of the accepted scientific systems but rather by preparational requirements. The preparation of specimens for natural history and building exhibitions has unlimited possibilities. The advances in technology are strongly felt in the museum field. We hope that this book will help the reader to explore ideas, learn techniques and understand the relationship between science and craft involved in the creative process that is the work of the preparator.
