Abstract
Abstract During this research, the catalogues of more than 200 libraries and museums of Hungary and its neighboring countries were examined. The authors calculated the amount and the size of the metadata and of the full content records in the databases of their collection management systems, as well as the size and the type of the full content data and the size of the databases. By analyzing the results, the goal was to answer the following three questions: (1) Can any significant difference be established between the results according to country, nationality, or type of institution?; (2) How large is a metadata record or a full content record?; (3) Is it possible to establish a methodology for selecting a representative sample of institutions to facilitate further research? For planning the costs of data management, the size of the databases, the number of metadata records, and the variability of metadata and media records shall all be considered. A distinction should be made between the indispensable “primary” data to be preserved for a long time, and the “secondary” data units which are derived from the primary data. It is investigated in this article how to establish the size of primary data in the databases of collection management systems.

During this research, the catalogues of more than 200 libraries and museums of Hungary and its neighboring countries were examined
The permission, and the technical skill, the authors have examined the catalogues of the customers of Qulto Companies, a Hungarian firm developing integrated collection management systems for libraries and museums in East-Central Europe
Technical data are searchable only by system librarians or by system managers, but they can only see their own databases, and most of the transaction records and the data structure of the application are hidden from them as well. Even if they can use the tools of the Operating Systems and the Database Management Systems, they do not have enough information about the data structure and the business logic of their ICMS to mine relevant information from their database
Summary
Abstract: During this research, the catalogues of more than 200 libraries and museums of Hungary and its neighboring countries were examined. A distinction should be made between the indispensable “primary” data to be preserved for a long time, and the “secondary” data units which are derived from the primary data It is investigated in this article how to establish the size of primary data in the databases of collection management systems. The causes of higher costs of Long-Term Preservation are the following: – bitstreams should be stored, and preserved in such a way that they remain useable and searchable, – Long-Term Preservation needs special planning and requires extra skills of the staff, – the selection of the relevant and important data requires time and human effort, – a database can be damaged; it is necessary to make backups from the different versions of the databases
