The Index Theologicus (IxTheo) is one of the most comprehensive open access databases for theology and religious studies, created and curated by the University Library of Tübingen in collaboration with (inter)national partners. This paper presents current developments that are taking IxTheo beyond its function as a pure search platform. Thousands of researchers already have personal profile pages within IxTheo, more than 500 of which contain a complete scientific oeuvre and a high proportion of open access publications. In future, authors will be able to curate their own pages - a step towards a personalized research service. At the same time, IxTheo is developing into a tool for research analysis: the systematic collection of metadata over centuries enables analyses of publication dynamics, thematic focal points and international research collaborations. A needs analysis has further confirmed the necessity of systematic documentation of DH- and AI-based theological research. IxTheo is therefore setting up its own collection for digital humanities and digital theology, in which projects, publications, research data and codes are documented - supplemented by regular DH lunchtime talks with international partner networks.
