Скачать или смотреть PRECIS Indexing: The Computer Age Breakthrough in Subject Indexing (Library Science Explained)

Step into the history of subject indexing with a deep dive into PRECIS (Preserved Context Index System). Developed in the early 1970s, PRECIS was a revolutionary system that bridged the intellectual power of the human indexer with the speed and consistency of the early computer age.

PRECIS solved the major problem of older methods, like Chain Indexing, by ensuring the full context of a document's subject was preserved in every single index entry.

🔑 What You Will Learn
The Big Idea: What PRECIS is and how it used computer manipulation to ensure full context preservation in every entry.

Core Logic: The principles of context dependency and one-to-one relationships that make the system work.

Indexing in Action: A step-by-step practical example using Role Operators and the Shunting technique to generate multiple, grammatically sensible access points from a single subject string.

Advanced Formats: Exploration of the Standard, Inverted, and Predicate Transformation formats.

Historical Context: How PRECIS replaced Chain Indexing in the British National Bibliography (BNB) in 1971, marking a major shift towards computerization and the MARC format.

The structural logic and emphasis on clear relationships in PRECIS offer valuable lessons for modern metadata, linked data, and semantic search today!
