The Master thesis focuses on the application of Information Systems in the field of Library and Information Science.  Within the context of organizational learning, a collaborative user-centered approach is used to produce desired system characteristics and future research suggestions. More specifically, this research study explores the library users’ and academic librarians’ perceptions of the current library discovery and access services as mediated through the Online Public Access Catalogue (OPAC) of the Academic Library of the School of Philosophy at Athens University in Greece. Additionally, it explores their desired characteristics for the ‘public facing’ Integrated Library System (ILS), of which the OPAC constitutes a module, in order to generate recommendations that guide the Academic Library staff members’ collaborative design of a more user-centered library information system. The study is built upon the systems thinking framework of Checkland’s Soft Systems Methodology (SSM). Applied theories and design processes guide research processes aimed at advancing both inclusive social learning and system improvements.
