PsycINFO Classification Categories and Codes

"Every record in PsycINFO® databases receives a classification code, which is used to categorize the document according to the primary subject matter. These classification codes can help you target your search by allowing you to restrict retrieval to a specific category. There are 22 major categories and 135 subcategories, and a list of codes. Each record is assigned to one or two classifications.
NOTE: This classification code system was designed to describe the content of the PsycINFO database, not the field of psychology."

Central Product Classification

"The name 'Central Product Classification' is intended to indicate that the purpose of CPC is to provide a framework for international comparison of various kinds of statistics dealing with goods, services and assets. Basically, CPC is intended to be used for different types of statistics, for example, industrial statistics and national accounts, price statistics, foreign trade statistics (including trade in services) and balance-of-payments statistics."

Book Industry Communication Standard Subject Categories

"The BIC Standard Subject Categories & Qualifiers scheme is the standard classification scheme for the UK book trade and other English language markets. Version 2.1 of the BIC scheme (BIC2.1) was released in December 2010. It updates and expands the previous Version 2.0. Note that all codes in BIC2.0 are included in BIC2.1 (although some headings have been modified, typically to update terminology or clarify scope)."

Newborn Screening Coding and Terminology Guide

"The goal of the Newborn Screening Coding and Terminology Guide is to promote and facilitate the use of electronic health data standards in recording and transmitting newborn screening test results. The Web site includes standard codes and terminology for newborn tests and the conditions for which they screen, and links to other related sites. The codes and vocabulary standards are provided in a series of tables that you can view on the Web and/or download for your own use.


"Nach dieser Systematik geordnet stellen zahlreiche Universitäts- und Fachhochschulbibliotheken ihre Bücher für die Benutzer frei zugänglich auf. Die GHB-Aufstellungssystematik wird ab Oktober 2004 nicht mehr aktualisiert und auf dem Stand vom 25. Juni 2004 eingefroren. Die für die Fachsystematiken federführenden Bibliotheken nehmen diese Aufgabe nicht mehr wahr."

"According to this system, numerous university and technical college libraries provide their books freely accessible to the users. The GHB installation system is not updated since October 2004 and is frozen at the status of 25 June 2004. The libraries responsible for the specialist systems no longer undertake this task "


"Die Umwelt-Klassifikation dient der inhaltlichen Erschließung von Objekten (Literatur, F&E-Vorhaben/ -beschreibungen, Rechtsvorschriften, …) im interdisziplinären Themenbereich 'Umwelt'. Sie ermöglicht deren Zuordnung zu bestimmten Umweltthemen und erleichtert damit ein treffsicheres aber gleichzeitig umfassendes (Wieder-) Auffinden. Diese Zuordnung erfolgt in der Regel als Metainformation in Verzeichnissen über den Ablageort der Objekte (z. B. Datenbanken, Bibliothekskataloge).

"The environmental classification serves the content development of objects (literature, R & D projects / legislation, ...) in the interdisciplinary thematic area 'Environment', which makes it possible to assign them to specific environmental topics, thus facilitating an accurate yet comprehensive (re- ) This classification is usually presented as a meta-information in directories about the storage location of the objects (eg databases, library catalogs) For clarification, the classification can be imagined as a group of 14 columns that symbolize the environmental areas (Eg, LU11, WA54)

Saffir-Simpson Hurricane Wind Scale

"The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term 'super typhoon' is used for tropical cyclones with sustained winds exceeding 150 mph."

Optics Classification and Indexing Scheme

"OCIS provides a flexible, comprehensive classification system for all optical author input and user retrieval needs. OCIS has a two-level hierarchical structure containing 36 main headers and approximately 1100 subcategories. OSA authors, presenters, and reviewers use OCIS to classify and index journal articles, meeting abstracts and presentations, and areas of research interest and expertise."

Surface Water Classifications

"Surface Water Classifications are designations applied to surface water bodies, such as streams, rivers and lakes, which define the best uses to be protected within these waters (for example swimming, fishing, drinking water supply) and carry with them an associated set of water quality standards to protect those uses. Surface water classifications are one tool that state and federal agencies use to manage and protect all streams, rivers, lakes, and other surface waters in North Carolina.
