The rapid development of digitalization of the library sector and the growing need to exchange bibliographic and authoritative data between libraries make it important to study metadata transfer protocols. This is especially true for consolidated library catalogs, which are important tools for integrating information resources of different institutions. In conditions when different libraries use heterogeneous automated library information systems (ALIS), the choice of optimal technological solutions for automating metadata retrieval is a critical task. The aim of the study was to compare the most common metadata extraction protocols: Z39.50, SRU/SRW, OAI-PMH, ILS-DI and API (using Koha API as an example), and to determine their advantages and disadvantages in the context of automating the formation of consolidated catalogs. The study showed that the oldest protocol, Z39.50, although it has extensive search capabilities and stability, is difficult to configure on the server side and technologically outdated. The SRU/SRW protocols, having inherited the key advantages of Z39.50, are more modern due to web technologies, but retain the same server implementation complexities. It has been established that OAI-PMH is an effective and simple solution for mass data acquisition, which is explained by the ease of setup and the use of standard web technologies. The API of modern LIS, in particular the Koha API, offers flexibility in interacting with data, but is characterized by a limited number of public methods and the need to create separate modules for each library system. At the same time, the ILS-DI protocol is effective for specific integration tasks, although it is limited in functionality. Prospects for further research are the creation of universal integration modules that can interact with different APIs and protocols of library systems, as well as the development of combined solutions for more efficient formation and maintenance of union catalogs.
