The aim of this thesis is to compare scholarly articles published in 2009–2019 that have used “information behavior” or “information practices” to denote the research, in order to gain a deeper understanding of how the two concepts have been used in the scientific literature. The research questions are: 1. What journals, countries and subject areas are the most prominent for each concept? 2. Which researchers constitute the research front of each concept? 3. What areas of interest can be distinguished within each concept? 4. What domain analytic similarities and differences can be seen between the two concepts? The study uses the bibliometric methods of author bibliographic coupling and co-occurrence analysis of author keywords, content analysis to determine subject areas and visualizations of networks using VOSviewer to examine the data. The results of the study indicate that information behavior is the dominating concept of the two. There are also indications of two separate research fronts in regard to researchers and their geographic locations. There is an overlap between the areas of interest of each concept. The general nature of the concepts, in addition to the different discourses that exist regarding them seems to be contributing factors to the confusion surrounding the definition, implication and use of each concept.
