Abstract

The Nuovo soggettario, the official Italian subject indexing system edited by the National Central Library of Florence, is made up of interactive components, the core of which is a general thesaurus and some rules of a conventional syntax for subject string construction. The Nuovo soggettario Thesaurus is in compliance with ISO 25964: 2011-2013, IFLA LRM, and FAIR principle (findability, accessibility, interoperability, and reusability). Its open data are available in the Zthes, MARC21, and in SKOS formats and allow for interoperability with l library, archive, and museum databases. The Thesaurus's macrostructure is organized into four fundamental macro-categories, thirteen categories, and facets. The facets allow for the orderly development of hierarchies, thereby limiting polyhierarchies and promoting the grouping of homogenous concepts. This paper addresses the main features and peculiarities which have characterized the consistent development of this categorical structure and its effects on the syntactic sphere in a predominantly pre-coordinated usage context.

Abstract

Nuovo Soggettario is a verbal subject indexing system renewing the existing Soggettario used in many Italian libraries. The renewal work consists of substantive improvements in the structure and the relationships of the system, now making it a true faceted thesaurus. Facet analysis is a key part of this development, both in identifying a set of facets and categories to which terms in the thesaurus belong, and in providing a scheme of the roles they can play within a subject string, as well as rules for their citation order.

Abstract

Psychologists, philosophers and linguists analyse concepts and investigate their relationship to words. Concepts are also relevant to the issue of bibliographic classification, i.e. "catagorisation". Examines from a chronological point of view the various theories for the analysis and organisation of concepts ranging from the Vickery developed in 1954, to Austin's hypotheses, to Ranganathan's "fundamental categories" and the contribution made by CRG, the Classification Research Group. Illustrates other approaches to categorisation such as Farradane's (relationship between couples of concepts) and calls for a closer study of categories and concepts.

Abstract

Presents a rebuttal of criticisms of the Italian version of Dewey's 20th ed., which in the section relating to the geography of Italy was alleged to have expanded and updated Auxiliary Table 2 by using classification methods that resulted in errors in the location of some of the country's 8.000 communes (Bibliotecario 38(1993), 147-148). The debate focuses on aspects such as the numbering system of classification, the use of subdivisions, whether or not to list all communes,and the absence in Italy of an intermediate entity between province and commune
