The Database of Byzantine Book Epigrams is an ongoing project that seeks to compile all metrical poems in Byzantine manuscripts that self-reference the book in which they are found. The database currently has over 12,000 records that record the epigram, the type of poem it is, and the manuscript in which it was found. There is a catalog searchable by occurrence, type of epigram, manuscripts, and people. There is also a substantial bibliography on Byzantine epigrams provided.
Logeion is a free online dictionary that aggregates the resources of all the Latin and Greek dictionaries available through the Perseus Classical collection in addition to other resources like the Dictionary of Medieval Latin from British Sources. A user can search by headword or an inverse search and use the tabs to switch between dictionary sources, including: Lewis and Short, Gaffiot, and others. The website also provides basic corpus analysis, offering examples of the word in sentences as well as providing morphological analysis. Though not all sources in the project are medieval, some, like the Dictionary of Medieval Latin from British Sources, are predominantly medieval.
