Keyword Subject Index

The Subject Index of over 20 000 entries has been compiled from keywords, names and formulae in the text and tables. It covers general classes of compound, specific compounds, general types of reaction, specific and named reactions, spectral and other properties, and other topics in heterocyclic chemistry. More details are again given at the beginning of the index in Volume 8. [Pg.6]

The key to solving the poster problem is in the proper use of the subject index of the abstracts. Such an index—in addition to an index of authors—was first provided in Utrecht (1984) and was subsequently included in the books of abstracts of most, but not all, symposia. The index is now compiled from keywords provided by the contributors. In San Diego (1998) keywords were requested, but ultimately an Index was not published. Such an index enables participants to... [Pg.42]

While in volumes 180 and 181 of this series several basic aspects of morphology, inter-phase structure and disorder were addressed, in the present volume, molecular interactions, modeling, phase transformation and crystallization kinetics are considered (see the subject index including keywords from volumes 180 and 181 at the end of the book). Needless to say, in spite of substantial success over 60 years or more we are still far from having a complete and unambiguous picture of polymer crystallization. We firmly believe that a fruitful approach to such a complex problem requires one to give way to many different and sometimes conflicting viewpoints, as we have attempted to do in these volumes. We do hope that they are not only a time-capsule left for... [Pg.313]

CASurveyor is a CD-ROM series of more than 1 5 informative summaries of worldwide science literature as published in CA. Each subject-specific topic can be searched using title, author, organization name, patent number, journal, publication year, document type, CA abstract number, keywords, and subject index terms. Abstracts, sequences, and molecular structures are display-able. [Pg.445]

Although they are only indirectly concerned with information retrieval from the literature, it is worth noting that the computer has also made significant contributions to the production of printed indexes. Much of the work has involved the production of traditional indexes by computer methods, ranging from simple Uniterm and keyword indexes to fully articulated subject indexes and dual dictionaries. Products more particularly of the computer age are permuted indexes such as the Permuterm Index of the Institute for Scientific Information and the KWIC, KWAC, KWOC family. [Pg.82]

The information on resistance is given as text, tables, and figures. The Uterature used by the authors is cited at the corresponding point. There is an index of materials as well as a subject index at the end of the book so that the user can quickly find the information given for a particular keyword. [Pg.419]

Fuel and Energy Abstracts. Available via ScienceDirect, also published bi-monthly in paper copy. Provides summaries of world literature on scientific, technical, environmental, and commercial aspects of fuel and energy. Covers over 800 international publications, monographs, conference proceedings, reports, surveys, and statistical analyses. Number of abstracts per issue can vary from 500 to 800. The online indexing is inconsistent. Individual abstracts are indexed in most issues. However, in newer issues, the citations are buried under headings, such as Liquid Euels, Heat Pumps, and Fuel Science and Technology, and cannot be retrieved without a secondary keyword search of the actual subject index of a particular issue. [Pg.474]

Biological Abstracts (University of Pennsylvania) contains much of chemical and biochemical interest, and publishes approximately 100,000 informative abstracts annually in semimonthly issues, each of which has an author index which cumulates in the last issue of each volume, and a guide to new books and periodicals. Each issue also has a subject index based on keywords in the titles of articles and arranged in alphabetical sequence by computer. This is supplemented by the classified arrangement of the material and a detailed table of contents. The computer-composed subject index cumulates each quarter. Specialized parts are also issued separately. [Pg.89]

Analysis processing starts with document analysis. In this process, a short summary (abstract) of the document is created along with keyword phrases, which provide simple natural-language access points for the subject content of the article. Also, the document analyst identifies the chemical substance and general subject index entries that capture the uniqueness of the document and provide the critical controlled-vocabulary, articulated subject access points. [Pg.288]

In its 90th year of publication, CA continues to provide concise summaries and extensive indexes of the major disclosures reported in journal articles, patents, symposia and conference proceedings, dissertations, technical reports, and books. The indexes in the weekly issues of CA are keyword, author, and patent indexes. The semi-annual (and five-year collective) indexes aie Author Index, Patent Index, General Subject Index, Chemical Substance Index, and Formula Index. The number... [Pg.289]

The General Subject Index (Fig. 20) differs considerably from the Keyword Index (Fig. 16) in the CA issues. [Pg.30]

However, if one lacks access to these, one may consult Chemical Titles and the keyword index (p. 1611) at the end of each issue of CA. In these cases, of course, it is necessary to know what name might be used for the compound. The name is not necessary for Index Chemicus (p. 1622) one consults the formula indexes. However, these methods are far from complete. Index Chemicus lists primarily new compounds, those which would not have been found in the earlier search. As for chemical Titles, the compound can be found only if it is mentioned in the title. The keyword indexes in CA are more complete, being based on internal subject matter as well as title, but they are by no means exhaustive. Furthermore, all three of these publications lag some distance behind the original journals. To locate all references to a compound after the period covered by the latest semiannual formula index of CA, it is necessary to use CAS-online. [Pg.1630]
