Alphabetical index of terms

After a listing of some general definitions relating to crystalline polymers (Section 1), the subject is divided into sections dealing, successively, with local structural arrangements at the scale of a few bond lengths (Section 2), morphological aspects (Section 3), molecular conformation within polymer crystals (Section 4) and, finally, kinetic aspects of crystallization (Section 5). An alphabetical index of terms is provided for the convenience of the reader.

The pol3rmers are identified by an alphabetical index in terms of manufacturer, product, state and activity in terms of weight percent in Table 2 different polymers from the same manufacturer are ninnbered, e.g.. Cl and C2 from American Cyanamid. 

Keyword list alphabetical list of terms describing the contents. It is used by the indexer during the database input as well as by the onliner during the search, because the spelling of the subject terms is laid dow precisely. 

The first appearance of the term "alkyd resin" in the subject index of Chemicaly bstracts 2iS. in 1929, under Resins. It was not until 1936 that Alkyd Resins was Hsted in its alphabetical place, but stiU appeared as "See Resinous Products." The proliferation of Hterature on alkyd resins peaked from the 1940s through the 1960s. Research activities on alkyds in the United States, as indicated by the number of pubHcations, has apparentiy tapered off since the 1970s. Readers interested in alkyd history can find more detailed historical reviews elsewhere (1 4). 

Numerous plastics are described in terms of manufacture and chemical and physical properties throughout this volume. Consult the alphabetical index. 

It is not suggested that the Handbook be read from cover to cover as an introductory text. The thematic approach should, however, enable readers to obtain a feel for the variety of terms encountered with any given aspect of an analytical measurement and the ways in which they relate to each other. For those who miss the more traditional alphabetical listing of definitions, the Index provides easy access to both the definitions and the accompanying examples. 

Conformity in spelling results in the same alphabetical order of chemical terms, irrespective of the language. A chemist frequently uses compilations of chemical data and subject indexes of journals and books of reference in languages other than his own. It is inconvenient to search for quinoline under q in an English journal, but under ch (Chinolin) in a German and under k (kinolin) in a Scandinavian journal. Even such small differences as thorium and torium, rhodium and rodium, rhamnose and ramnose are inconvenient and may cause important references to be missed. 

In this paper indexing is defined as a system which provides leads to needed information by the three steps—selection of appropriate terminology (most of which is usually found in the material being indexed) modification of the selected terms by suitable words and phrases and alphabetical arrangement of the selected terms and their modifications. 

Individual alternative terms cause relatively little difficulty in comparison with the difficulties arising when the information needed is not restricted to a single person or compound. Often, in using the chemical literature, the characteristics of several related compounds or of a class of compounds are required. In this situation, an alphabetized index may compel the examination of a number of different headings. Searching around for all of the compounds making up a class can, on occasion, become quite burdensome and may prove to be so laborious that it constitutes a task which is economically impossible to undertake. 

Compiled with the aid of EC, UK, US and Canadian official lists, DOSE is being published in seven alphabetical volumes, and is to be completed by 1995. The final volume will contain an index of chemical names, CAS registry numbers and molecular formulae. Each volume will also contain glossaries of biological organisms, chemical toxicology and ecotoxicology terms,... 

The Keyword Index consists of a series of words and phrases selected from the title and text of the abstract (Fig. 16). Subject terms and substance names are listed alphabetically. The substance names included in the Keyword Index seldom correspond to the systematic CA Index Names. They can be trivial or semi-systematic names, but are, in each case, the designations used by the author in his paper and thus also included in the CA abstract. Only the volume indexes of the Chemical Abstracts contain the systematic substance names.
