Slide Classification System for the Organization and Automatic Indexing of Interdisciplinary Collections of Slides and Pictures

"Almost all disciplines make extensive use of the resources provided by slide libraries and picture collections. Growing demands for pictorial material have stimulated a concern for making slide and picture collections more useful and more usable by better physical arrangement and more thorough indexing. The system provides a classification scheme for the organization of general collections of slides and pictures with a broad subject coverage as opposed to the more typical slide classification system which deals with a single subject field.

Cancer Biochemistry and Host-Tumor Interactions: A Decimal Classification

"This is a hierarchical decimal classification of information related to cancer biochemistry, to host-tumor interactions (including cancer immunology), and to occurrence of cancer in special types of animals and plants. It is a working draft of categories taken from an extensive classification of many fields of biomedical information. Because the classification identifies very small areas of cancer information, it can be used for precise matching of cancer researchers with useful documents or data in information systems, and for detailed analysis of large cancer research programs."

Thesaurus of Development Communication

"This controlled vocabulary comprising approximately 1,030 terms commonly used in the field of international development communication was created by the Clearinghouse on Development Communication of the Academy for Educational Development to analyze and index documents. This standard list of terms, designed to provide subject access to information in this area, was constructed by extracting key concepts from relevant documents. The initial list was revised after testing for precision and recall, and reviews by clearinghouse personnel and other subject experts.

The Application of the International Classification of Diseases to Dentistry and Stomatology (ICD-DA) is intended to provide a practical and convenient basis for the classification and coding of data by all those working in the field of oral and dental disorders.

Medical and Health Related Sciences Thesaurus

"The Medical and Health Related Sciences Thesaurus is the list of indexing terms developed and maintained as an integral component of CRISP (Computer Retrieval of Information on Scientific Projects), a comprehensive system furnishing scientific data on all research projects supported by the Public Health Services. CRISP is operated by the Research Documentation Section, Statistics and Analysis Branch, Division of Research Grants.

Army Medical Library Classification Medicine

"The Classification covers the field of medicine and its related sciences. With it are used the various schedules of the Library of Congress Classification in order to provide an orderly arrangement for subjects bordering on medicine and for non-medical reference books. The LC schedules are used extensively; for example, social questions relating to the blind and the deaf are classified in HV (Social Sciences). When classification according to the LC schedules is indicated, only the class letters have been furnished in the present index.

Petroleum Abstracts® Exploration and Production Thesaurus

"The E&P Thesaurus is a collection of words and phrases that are descriptive of the concepts and equipment pertaining to petroleum exploration, development and production, exclusive of geographic areas and named geologic terms, which are included in the Geographic Thesaurus and its supplement. Further, the E&P Thesaurus is a controlled vocabulary for this subject area, in which the various concepts have been linked by means of generic or hierarchical relationships. These relationships may be truly generic or may be associations by use, or even convenience.

The Dana classification, assigns a four-part number to a mineral species. First is its class, based on important compositional groups; next, the type gives the ratio of cations to anions in the mineral; finally, the last two numbers group minerals by structural similarity with a given type or class."
