Due to the popularity of these library material, video games are becoming more common in library collections. Libraries must devise proper ways of processing this type of materials which is including their selection and procurement, bibliographic and content processing, preservation and use. These special collections allow users to use video games, but can also be used for research purposes or to obtain information about purchasing certain video games on their own. Most research projects that are currently underway in the world are mostly focused on the preservation of video games as cultural objects, however parallel to this kind of research, for the purpose of preservation, researches are also being conducted to properly describe this type of library material. Results of this researches have brought the basic elements of description that fit the needs of the end user. As there is no standardized controlled vocabulary used for subject indexing, most of the current research is focused on trying to make and perfect these vocabularies to be used within the library and any institution engaged in aggregating and selling video games. This is because each commercial site that sells or reviews video games uses its own terms for the subject terms and these subject headings can’t be used because there are too many differences in the assigning of terms. The purpose of this thesis is to analyze description elements of video games and to compare them with elements of ISBD, but also to indicate problems that occur in the cataloging of video games. Therefore, bibliographic and subject elements were analyzed on examples of records from catalogs of Public library in Zadar (GKZD), Zagreb City Libraries (KGZ), WorldCat, and on a self-made example by using a metadata schema UW/SIMM. The main assumption in this analysis is that there will be a difference between examples and that there will always be a lack of elements in the records that are relevant within the specified metadata scheme.
