56 Omejitve raziskave: Nereprezentativni vzorec in nezmožnost posploševanja ugotovitev. Ključne besede: online katalogi, gesljenje, informacijsko vedenje, razumevanje, individualne razlike Abstract Purpose: The aim of the article is to identify the relevance of subject headings in the online library catalogue (OPAC) and to verify the hypothesis that the database structure and the search language is more in favour of natural and technology sciences researchers than to researchers in the field of humanities. Methodology/approach: The study was held in a controlled environment. It took place between autumn 2009 and spring 2010. 13 undergraduate and 7 graduate students of chemistry and psychology participated. A stratified sample was used. Data were collected by the system log. We also recorded the entire screen image and sound. Participants also answered a survey questionnaire. Content analysis was carried out. Linking of the identified categories and the theoretical framework of the research context followed. Results: The survey results showed no significant difference between the information seekers of the scientific fields considered. However, they showed the importance of the user's knowledge of information systems and the availability of resources. A lack of confidence in these results, the strong influence of internet search engine Google, and the lack of awareness on the existence of subject headings were identified. Consequently, it was impossible to test the hypothesis. Research limitation: Unrepresentative sampling, inability to generalize the findings. Keywords: OPAC, indexing, information behaviour, understanding, individual differences 1  Uvod Uspešnost iskanja po vsebini v knjižničnih informacijskih sistemih, kot je COBISS, je v veliki meri odvisna od tega, kakšna je kakovost vsebinske obdelave v le-teh. Za is- kanje po vsebini so zelo pomembni elementi, ki jih v sklopu vsebinske obdelave v kataložne zapise dodajajo katalogizatorji v obliki predmetnih oznak, deskriptorjev, ključnih besed ali klasifikacijskih oznak. Pri tem si strokovnjaki-katalogizatorji poma- gajo z že obstoječimi sistemi, kot so npr. razni kontrolirani slovarji. Kakovostno vse- binsko obdelavo ter posledično kakovostno iskanje po vsebini je mogoče zagotoviti A.
