The importance attached to subject indexing in library services, librarian awareness of its social role and practical purposes,attention to indexing practices and the use of catalogs: How are these elements reflected in the system of rules governingsubject indexing in Italy? What does “rule following”, to use Wittengenstein’s well-known expression, mean in our field?Why and how do we follow a rule? In which sense is following a rule a practice? How and in which conditions does therule relate to the practice and vice versa? Beginning with these questions, the main features of the Italian subject indexingrules are illustrated: explicit rules, based on linguistic criteria, contain justifications for why a given rule should be followedand should be sensitive to the use-context. All three of these features imply a relationship with practice; at the same time,the rules presuppose a social practice in which they are employed and express their pragmatic meaning. Thus, the indexingrules are manifested in the language of indexing through the means by which this language is used; that is, in the indexingactivity and in the use of catalogs. Hence, the call for libraries to attend to the pragmatic dimension of subject indexing.
