The aim of this thesis is to analyse the possibility to identify the FRBR entity expression from existing catalogue records performed within the context of Swedish cataloguing rules. The empirical study uses a sample of records from the catalogue within the library at the University College of Borås. To begin with, the thesis reports some of the earlier discussion about the FRBR model. That gives an understanding of which problems the model has and justifies the study?s delimitation towards expression. The research questions in the study ask to what extent it is possible to distinguish expression, what fields that identify the entity and if descriptions of particular types of media and publication are different in respect of expression. For an understanding of the empirical material the study uses categories fetched from the article FRBRization: A method for turning online public finding lists into online public catalogs written by Martha M. Yee. The result shows that expression can be identified in a large part of the material. At the same time, the result shows a clear difference between descriptions of monographs and serials, respectively. They are different both in respect of to what extent expression can be distinguished and which fields that identify the entity. One possible interpretation of the result is to understand the concepts in FRBR as roles rather than things. That seems to be able to solve some of the problems that are connected with the model.
