Stemmaweb – online tools for empirical stemmatology

Welcome to, a resource for textual scholars to explore the transmission of their texts. The set of tools hosted here has grown out of the Tree of Texts, a CREA (“creative research”) project funded by the KU Leuven from 2010–2012, and is now hosted in Switzerland via the SWITCH academic cloud service. The source code for all tools and associated libraries is available on Github, and the tools themselves are free for use by any interested scholar.
