PREFACE

CRC HANDBOOK OF CHEMISTRY AND PHYSICS

102nd Edition

The Handbook as an Integrated Data Resource for the Future


This 102nd Edition of the CRC Handbook of Chemistry and Physics continues our dedication to maintaining the highest standards of quality, completeness of coverage, and diversity. Before looking into the future, let us first look at the diversity of the present CRC Handbook.

The demand for digital access to high-quality data in chemistry and physics keeps growing as knowledge discovery, artificial intelligence, data mining, and advanced modeling have become routine tools. The CRC Handbook is as valuable as it has ever been. What are we doing to ensure that the highest quality data is available not only now but also into the future?

Our commitment continues to use the tools of the Information Revolution – advanced database methods and Web technology – to ensure the widest possible distribution and usability of the CRC Handbook, which is now available 24 hours a day, every day, regardless of user location. The future is bright. Usage continues to grow, and the CRC Handbook is growing to meet today's demands. We continue to explore new developments to meet these growing digital demands.

The success of the CRC Handbook is very dependent on feedback from its users. The Editor-in-Chief appreciates any suggestions from readers on proposed new topics for the CRC Handbook or comments on how its usefulness may be improved in future editions. Please send your comments to [email protected]

Numerous international experts make key contributions to the CRC Handbook every year. Their efforts play a key role in the quality and diversity of the subject matter covered in the CRC Handbook. The sound advice and guidance of the Editorial Advisory Board members are very much appreciated.

Fiona Macdonald, Senior Publisher – Chemical & Life Sciences, CRC Press/Taylor & Francis Group has been of great assistance and support in providing oversight to ensure that the CRC Handbook continues to satisfy the needs of the user community. Thanks are also due to Linda Manis Leggio and Pam Morrell for their detailed, cooperative work and extreme care in the production of the printed CRC Handbook. Special thanks are due to Associate Editors Maria J. Doa and Thomas Bruno for their assistance, especially in the area of laboratory chemistry and chemical safety.

Finally, this 102nd Edition of the CRC Handbook is a tribute to David Lide, Editor-in-Chief from 1990 to 2009. His dedication to providing generations of scientists with the highest quality of data is a tradition I hope to continue.

Searching for Chemicals and Properties

The CRC Handbook of Chemistry and Physics (HBCP) contains over 700 tables in over 450 documents which may be divided into several pages, all categorised into 17 major subject areas. The search on this page works by searching the content of each page individually, much like any web search. This provides a challenge if you want to search for multiple terms and those terms exist on different pages, or if you use a synonym/abbreviation that does not exist in the document.

We use metadata to avoid some of these issues by including certain keywords invisibly behind each table. Whilst this approach works well in many situations, like any web search it relies in the terms you have entered existing in the document with the same spelling, abbreviation etc.

Since chemical compounds and their properties are immutable, a single centralised database has been created from all chemical compounds throughout HBCP. This database contains every chemical compound and over 20 of the most common physical properties collated from each of the >700 tables. What's more, the properties can be searched numerically, including range searching, and you can even search by drawing a chemical structure. A complete list of every document table in which the compound occurs is listed, and are hyperlinked to the relevant document table.

The 'Search Chemicals' page can be found by clicking the flask icon in the navigation bar at the top of this page. For more detailed information on how to use the chemical search, including adding properties, saving searches, exporting search results and more, click the help icon in to top right of this page, next to the welcome login message.

Below is an example of a chemical entry, showing its structure, physical properties and document tables in which it appears.
