The issuance of a new edition of a technical reference text usually signifies that the material in the book has provided repeated value-added information to the reader/buyer. It is a benchmark for the editors, authors and contributors that they in fact participated in a significant way to the progress of science, engineering, and technology. It is highly gratifying to get calls and letters from one's peers, years after publication, addressing content, errata, further topics of interest, etc. all this despite the fact that the polymer and plastics field continues to advance at such a rapid pace that the written word is obsoleted on the day of public release. Additionally, new data and information is communicated so much faster and easier through electronic means that the need to update an old text seems a Sisyphean task.A new edition does however allow the correction of oversights and mistakes, the inclusion of new information and data and, as a result of time and tide, the contribution of new authors, their new perspectives and styles. Thus the text becomes refreshed, modernized, able to serve the readership's needs for valuable information and understanding.
