PRAVILNIK ZA OPIS I PRISTUP GRAĐI U KNJIŽNICAMA, ARHIVIMA I MUZEJIMA I OPIS ONLINE NEOMEĐENE GRAĐE: MOGUĆNOSTI PRIMJENE U NACIONALNOJ I SVEUČILIŠNOJ KNJIŽNICI.

The aim of the paper is to analyze and assess the possibility of applying the stipulations of the Code for description and access to resources in libraries, archives, and museums (the LAM Code) for the description of online continuing resources at the National and University Library in Zagreb in relation to the existing standard and practice. Online continuing resources, which include integrating and serial publications, have been part of the legal deposit since 2004. At that time, the National and University Library in Zagreb (NUL) established a work process of capturing, cataloguing and longterm archiving of online publications in the NUL digital systems, thus making them a part of the Library's holdings. The previous practice of cataloguing according to the consolidated edition of the ISBD prescribed the content of the data for the bibliographic description. The LAM Code, which is based on the conceptual models of three heritage communities, represents a completely new way of perceiving resources as an object through the entity-relationship principle and, accordingly, makes stipulations for uniform and standard data formatting for the description of different types of resources. Uniformly formatted data is a prerequisite for functional interoperability and reuse in different digital environments. Methodology. The analysis is based on the testing that was conducted during the fall of 2022, the purpose of which was to assess the applicability of the LAM Code to different types of library material owned by the NUL. As part of the aforementioned testing, 10 test bibliographic records for continuing resources (in print and electronic form) were created, which served as a starting point for the analysis of the application of the LAM Code to the description of online continuing resources. The results of the analysis have shown to what extent the application of the KAM Code is in accordance with the existing practice of cataloguing in the NUL, that is, whether and to what extent it requires modification. The analysis does not cover the aspect of the format or the information system. Social impact. The evaluation of the LAM Code application for the creation of records for online continuing resources, which have been processed at the NUL for over twenty years and is covered by the legal deposit provisions within the Croatian Act on Libraries and Library Activities, is an important segment in the future workflow of processing library materials at the NUL. The paper aims to establish potential differences in current practice with regard to the unique task and role of the NUL in collecting and long-term storing of online continuing resources.
