Lege

Tolle, lege. — Take up and read.

Lege is the free online library of the Aquinas Institute. It presents the Latin works of three Doctors of the Church side by side with their translations, so that the original text and the translation can be read together, line by line.

Reading requires no account and nothing is sold. The library exists for scholars, students, clergy, and anyone who wants to read these authors in their own words.

About

The library is published by the Aquinas Institute for the Study of Sacred Doctrine, a non-profit Catholic academic publisher known for its bilingual Latin–English edition of the works of St. Thomas Aquinas. Lege makes the Institute's texts available online at no cost.

The three collections previously lived at aquinas.cc, augustinus.cc, and albertus.cc. Those addresses now lead here. Bookmarks and citations to the old addresses continue to work.

Translations are prepared by the Institute's editors and volunteer translators from the Latin, reviewed, and published progressively. Where a translation is incomplete, the Latin text is still available.

Reading and searching

Each collection opens on a table of contents. Choose a work, then a book, question, chapter, or sermon.
The Latin and the translation are shown in parallel columns. Columns can be chosen and hidden.
Every passage has a stable address that can be cited and shared, and a plain-text edition of every work for printing and reading offline.
Full-text search covers the Latin and every translation in all three collections at once.
Accounts exist only for editors and translators who contribute to the texts. Readers never need to sign in.
