"Basilica Online is a fully-searchable online edition of the 17 volumes of the Basilica text and its scholia, as edited between 1945 and 1988 by H.J. Scheltema, D. Holwerda, and N. van der Wal. The Basilica is the single-most important source for Byzantine law throughout the period of the Byzantine empire, and is a major source for Byzantine studies more broadly." See
