General Features

For those who have not used Diogenes before, it has a number of useful features:

It’s Free

Diogenes is free, open-source software (GPL v3).

Deep Integration of Morphology and Lexica

Click on any word and get a morphological analysis along with the corresponding entries in the LSJ (Greek) or L-S (Latin) lexicon. In the lexicon entries, click on a citation to jump to the context (where possible). It is also possible to perform morphological searches (i.e. to search for all or selected inflected forms of a given word). Morphological data comes from Perseus.

Powerful Searching

You can create groups of texts to search within (and for the TLG, you can select by date, genre, etc.). You can jump from search results right to the context of each passage. You can search for words in any order within a given scope and delimit that scope by punctuation or number of lines.

Efficient Reading

It’s easy to open up a given passage of any Greek or Latin text and start reading with the lexicon a click away, or to browse through the dictionaries to look up a word.
