Hacettepe University is the most productive institution of Turkey in terms of scientific publications which are included in the citation indexes. In this study, Hacettepe University- addressed publications are analyzed with regard to their bibliometric features from the year when first Hacettepe University-addressed publication took its place in citation indexes (1968) to 2009. Bibliographic data obtained from these were evaluated by the social network analysis method. Social network analysis is an interdisciplinary study and is often used in many different fields. It also examines the structure of communities, tries to describe the constructions of networks and models the existing connections by visualizing the relationships between the communities. Following research questions were addressed in this study: 1) What is the level of productivity of Hacettepe University in terms of scientific publications within the scale of Turkey and is there any change over time? 2) In which fields and journals do the members of Hacettepe University make publications most frequently? 3) What is the tendency of co-authorship for Hacettepe University-addressed publications and is there any change in the number of authors over time? 4) What other institutions do the authors of Hacettepe University collaborate most frequently? 5) In which countries do the authors who most frequently collaborate with Hacettepe University work? 6) Who are the most productive Hacettepe University-addressed authors in the citation indexes? Besides answering these research questions, co-authorship networks and institutions that were collaborated with are visually demonstrated via CiteSpace, which is an open-access social network analysis software. These attempts of visualization, along with the evaluation of the publications that were produced by the universities, will serve as a data source for the studies that aim to build a publication policy.
