The volume of available bibliometric data is constantly increasing due to the high number of scientific publications (articles, announcements, monographs, etc.) that each year are produced and are deposited in the various information systems and repositories. The main source of bibliometric data is the citation indexes. such as Scopus, Web of Science and Google Scholar. Citation indexes offer various bibliometric indicators as well as the ability for researchers to process raw data to create new metrics or perform bibliometric studies. Access to primary bibliographic data is provided through an API and is free or it is provided via subscription, depending on the provider. In the present thesis, a bibliographic review will be conducted regarding the citation indexing capabilities in the provision of bibliometric data. Then the bibliometric application that has been created in the Information Management Laboratory of the Department of Archives, Libraries and Information Studies (University of West Attica) will be further extended to be able to extract additional categories of data from the Scopus citation index. In addition, an attempt will be made to collect additional bibliometric data in order to enrich the capabilities of the bibliometric tool. The departments and staff of the University of West Attica are selected as the field of application. The thesis will be completed with the evaluation and commentary of the results, the drawing of conclusions and proposals for future expansion.
