Storage of Polymer Structures. CAS has developed comprehensive sets of nomenclature rules and structure conventions that have become standards in the world of chemical literature (see Chemical Abstracts Service Information System). CAS selects polymers for indexing according to a set of rules (5). The Registry File records are created from chemical information published in books, patents, dissertations, scientific journal articles, etc.

In full-text databases the complete articles can be retrieved. They contain the complete text of a documentation unit. In most cases this text is completed with additional data-fields, e.g., descriptor, thesauri, classification code fields. An example of a full-text database is the CJRSC (Chemical Journals of the Royal Society of Chemistry) which is offered by STN. The document, shown in Search Example 2 on the topic of waste removal, is abbreviated. Apart from bibliographic information (author [AU], title [TI], source [SO], abstract [AB]) the full article with tables and figures can be retrieved. The information found is very comprehensive but also expensive in comparison to bibliographic databases (see Chemical Abstracts Service Information System and Inorganic Chemistry Databases).
