Logeion allows searches of a series of Greek and Latin dictionaries and classical reference works. It was developed beginning in 2011 at the University of Chicago by students Josh Goldenberg and Matt Shanahan under the direction of Professor Helma Dik, and regularly adds new features and resources. Inspired by the innovative Dictionnaire vivant de la langue française, also based at the University of Chicago, it began with a nucleus of several reference works originally digitized by Perseus.
Housed at the Université catholique de Louvain, Hodoi Elektronikai: Du texte à l'hypertexte is a freely-available digital repository of ancient Greek texts, intended especially for students of language and history. It is part of Leuven’s Bibliotheca Classica Selecta—overseen since 2015 by Paul-Augustin Deproost of Université catholique de Louvain—which also houses the Latin-language site Itinera Electronica. Bibliotheca Classica Selecta was begun in 1992, and the Greek texts were uploaded into the environnements hypertextes of Hodoi Elektronikai between 2005 and 2010.
In June of 2016, the Thesaurus Linguae Graecae (TLG) launched a redesigned interface through which to access its ever-expanding corpus of Greek texts beginning with Homer and ending with the fall of Byzantium. Subscription users get access to the full corpus—currently comprised of roughly 10,000 works associated with 4,000 authors. An abridged database is open to the public free of charge, as are digital versions of the LSJ, Cunliffe’s Lexicon of the Homeric Dialect, Powell’s Lexicon to Herodotus, and the Austrian Academy of Science’s Lexikon zur byzantinischen Gräzität. The TLG allows users to search and browse texts, consult lexica, explore N-grams, and generate statistics and vocabulary tools for selected texts. All users, even those accessing through an institution, must create a personal account to access any part of the TLG.
