Hungarian National Shared Catalogue (MOKKA)

MOKKA is the shared catalogue of the Hungarian national, scientific, academic libraries, and the institutions (county and city libraries) providing central services. Its main scope is the elimination of redundant cataloging practices. Libraries can both upload and download their bibliographic records, which are deduplicated by MOKKA - thus the final result of such a process is a standard, coherent register for Hungarian libraries.

The bibliographic database includes more than 4 million records from 67 library collections.

The project development phase included the process of metadata harvesting and the creation of search and retrieval functions. The National Document Supply System has integrated to the database more than 10 million record items together with loan status information. The project also included the development of inter library loan tools and library register workflows. Currently the system is managing 10 000 requests quarterly.
