Institutional repositories in Canadian post-secondary institutions User interface features and knowledge organization systems

Purpose - The purpose of this paper is to examine and provide an insight into Canadian post-secondary institutional repositories (IRs) with respect to user interface features and knowledge organization systems (KOS) used. Design/methodology/approach - The approach is to explore all Canadian post-secondary institutions and their user interfaces to establish the type of searching and browsing features they have used and whether or not they have made use of KOS such as subject heading lists or classification schemes. Findings - A directory of 27 IRs in Canada is created. Incorporation of KOS in institutional repository is evaluated. The examination is focuses on accessibility, searching, KOS use, and retrieval. Evaluation shows that few IRs, have incorporated complex KOS such as controlled vocabularies. Browsing and searching options are available, but user interfaces are usually not modified to enhance information retrieval. Originality/value - This is the first paper examining Canadian IRs from the perspectives of searching, browsing and the use of KOS.
