Bibliographic databases have recently received increased attention from researchers which explore the possibilities of data-driven research based on bibliographical data. This paper briefly overviews the current state of digital literary studies and tries to summarize the development and current situation of data-driven research on bibliographical databases which led to the emergence of so-called bibliographical data science. The specific problems of quantitative research on bibliographical data both from the methodological as well as technical point of view are discussed in more detail and intensive dialogue between data curators and data researchers is advocated for. Subsequently, practical examples of bibliographical data analysis are shown on an example of the data from Czech Literary Internet database and the Statistical and Analytical module for bibliographical data analysis newly developed by the Czech Literary Bibliography research infrastructure is introduced.
