Logeion is an open-access database of Latin and Ancient Greek dictionaries.^[1] Developed by Josh Goldenberg and Matt Shanahan in 2011, it is hosted by the University of Chicago. Apart from simultaneous search capabilities across different dictionaries and reference works, Logeion offers access to frequency and collocation data from the Perseus Project.

Features

Having started out as an aggregator for Latin and Ancient Greek dictionaries, Logeion has implemented multiple new features in its development. These include:

• the integration of reference works on antiquity;
• frequency and collocation data from the Perseus Project;
• corpus examples, equally retrieved from the Perseus Project;
• references to relevant chapters in a number of (English-language) textbooks.

Furthermore, an iOS app was developed by Joshua Day in 2013. The app's second version, launched in 2018, is also available for Android devices.
