We are pleased to present Stemmaweb, which was developed in cooperation with members of the Interedition project and which provides an online interface to examining text collations and their stemmata. Stemmaweb has two homes:
http://treeoftexts.arts.kuleuven.be/stemmaweb/ (the official KU Leuven site)
http://byzantini.st/stemmaweb/ (Tara’s personal server, less official but much faster)
via The Tree of Texts | Empirical investigations into recovering text history.
