How to get a headstart on new projects.
There's a lot of information scattered around the world that can help you, if only you can find it. That's the job for Lockheed's Dialog, the world's leading online information retrieval system. This computerized sleuth puts you in instant touch with more than 180 databases and provides abstracts of journal articles, conference papers, research reports, patents and news stories^and all of this information goes back over 15 years. Dialog covers virtually every field, from alkaloids to polymers to zinc. All you need to use Dialog is a standard computer terminal and a telephone. Your library probably subscribes to Dialog. Involved in some phase of a new project!" Better get involved first with Dialog. It can save you time, money and effort—and lots of each.

ries shows that this is not the focus of the books, although chemical reactions are more incidentally than primarily covered in the different topics included in this series of reviews. An intent to circumscribe the use of the term derivatization to the more restricted and somewhat traditional meaning in chromatographic situations does not seem to dominate either, since the chapter on flow injection analysis puts a different dimension into the topical selection. The question then is what is the scope of this series? The editors owe an answer to their readers. The first chapter in this collection of reviews (by Bo Karlberg) is a good and rather balanced introduction to flow injection analysis, the unsegmented version of continuous-flow sample processing. The second chapter (by G. Schill and D. Westerlund) covers ion-pairing reactions. Chapter 3 (by L. D. Bowers and W. D. Bostick) deals with immobilized enzymes as precolumn and postcolumn modification reagents in liquid chromatography. Chapter 4 (by W. F. Lindner) offers a very useful and well-organized overview on the resolution of optical isomers by gas and liquid chromatography. Chapter 5 (by J. F. Lawrence) which, together with chapter 4, in this reviewer's perception is the most valuable of these reviews, deals with prechromatographic chemical derivatization in liquid chromatography. The final chapter (by B. D. Page and H.B.S. Conacher) is a critical evaluation of the pros and cons of derivatization as applied to the restricted field of chromatographic determination of food additives. Each of the six reviews offers a useful starting source for those interested in the specific subjects covered. Organic Elemental Analysis. Wolfgang K i r s t e n . xii + 146 p p .

Reviewed by Warren Crummett, Main Building 574, Analytical Laboratory, Dow Chemical Co., Midland, Mich. 48640 This book is a detailed description of the microanalytical techniques currently being used in the author's laboratory, in the hope that both the research analyst and the industrial analyst will benefit from its use. Certainly the author succeeds in describing the methodology of his laboratory. General techniques are described and discussed in detail. These include chapters on reagents and standards; transfers of solutions; drying, weigh-

Characterization of Highly Cross-linked Polymers
se>N S.S. Labana and R.A. Dickie, Editors Ford Motor Company Surveys the considerable progress made in characterizing and understanding highly crosslinked polymers. Explores new approaches in tracking molecular structures and discusses various characterization techniques such as solid-state NMR. IR spectroscopy, and electron spin resonance. Characterizes not only chemical formation processes of highly cross-linked polymers but also the chemical changes accompanying degradation processes.
