The project of developing the COBISS.SI General List of Subject Headings (SGC) has been running since 2000, in cooperation between the Institute of Information Science (Institut informacijskih znanosti, IZUM) and six Central Specialised Information Centres.
The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries.
The Institute of Information Science (Institut informacijskih znanosti, IZUM), Maribor, and six Specialised Information Centres operating within the University of Ljubljana, and the Scientific Research Centre of the Slovenian Academy of Sciences and Arts participate in the project described in this article.
An assessment of the Splošni slovenski geslovnik (Slovenian general list of subject headings), published by the National and University Library (NUK) in 2000, is dealt with in this article. The analysis of the NUK subject headings list is made in the light of individual principles comprised in 1999 IFLA’s Principles Underlying Subject Heading Languages (SHLs).
The first part gives an overview of the development of the Library of Congress subject headings system from its beginnings, over one hundred years ago, to its place and role in the present-day online catalogues.
