PRECIS (Preserved Context Index System)

PRECIS (Preserved Context Index System)

PRECIS (PRESERVED CONTEXT INDEX SYSTEM)   PRECIS is an acronym for PREserved Context Index System or PREserved Context Indexing System. PRECIS is a computer assisted pre-coordinate subject indexing system developed by Derek Austin in 1968 as a result of long research which the Classification Research Group (CRG) undertook to give a new general classification for information control. In 1969 British librarians Derek Austin and Peter Butcher issued PRECIS: A rotated subject index system, published by the Council of the British National Bibliography. This appears to be the first published report on an innovative method for adding subject data in the form of descriptors to the computerized MARC record. This system is considered as the most important development in alphabetical approach to subject specification in recent years.

The system aims at providing an alphabetical subject index which is able to cater to the variant approaches of the users along with their context. In order to achieve this objective, the system arranges the components of a document,  into a significant sequence, thus, all the important components in the string are used as approach points. Simultaneously, the terms are displayed in such a fashion that every term is related to the next term in a context dependent way. Moreover, the system is amenable to computer operation, which further adds to the advantage of the system as the entries will be prepared and arranged automatically by the computer.

WHAT ARE THE BENEFITS OF RDA? / WHY IS RDA NEEDED?

[Main article: Resource Description and Access https://librarianshipstudies.blogspot.com/2017/07/resource-description-and-access.html]

=> RDA builds on the strengths of AACR2 but has some new features that make it more useful for description as a cataloging code for the digital environment in which libraries now operate.

=> RDA is better at catering for digital resources and for resources with multiple characteristics and will provide more guidance on the creation of authority headings.

=> RDA has been developed with the end-user in mind.

=> RDA provides a consistent, flexible and extensible framework for the description of all types of resources, including digital resources and those with multiple characteristics.
RDA is compatible with internationally established principles, models, and standards.

Resource Description and Access

Resource Description and Access

Glossary of Library & Information Science - RESOURCE DESCRIPTION AND ACCESS (RDA) ➨ RDA stands for “Resource Description and Access” and is the title of the standard, that is the successor to AACR2. Resource Description and Access (RDA) is a standard for descriptive cataloging providing instructions and guidelines on formulating bibliographic data. Resource Description & Access (RDA) is a set of cataloging instructions based on FRBR and FRAD, for producing the description and name and title access points representing a resource. RDA offers libraries the potential to change significantly how bibliographic data is created and used. RDA is a standard for resource description and access designed for the digital world. It provides (i) A flexible framework for describing all resources (analog and digital) that is extensible for new types of material, (ii) Data that is readily adaptable to new and emerging database structures, (iii) Data that is compatible with existing records in online library catalogs. RDA is a package of data elements, guidelines, and instructions for creating library and cultural heritage resource metadata that are well-formed according to international models for user-focused linked data applications.  RDA goes beyond earlier cataloging codes in that it provides guidelines on cataloging digital resources and places a stronger emphasis on helping users find, identify, select, and obtain the information they want. RDA also supports the clustering of bibliographic records in order to show relationships between works and their creators.
