To find a text in Latin, search in TRIPOD, the tri-college library catalog.
You can search by Author or by Title
1) Loeb Classical Library
A series of Latin and Greek texts with facing page English translations. Now published by Harvard University Press but started in 1912 by the publisher William Heinemann. The critical apparatus is minimal at best and should be supplemented by a more scholarly edition.
2) Oxford Classical Texts - Search Scriptorum classicorum bibliotheca Oxoniensis A series of Ancient Latin and Greek texts with critical notes. In recent years introductions appear in English; earlier introductions were in Latin.
3) Cambridge green and yellow series - Search: "Cambridge Greek and Latin Classics" A series of Ancient Greek and Latin texts with commentaries that address literary issues as well as grammatical ones.
4) Teubner Series - Search Biblotheca scriptorum Graecorum et Romanorum Teubneriana. Also a series of Ancient Latin and Greek texts with critical notes. Teubner has been publishing longer than Oxford and has the greatest number of texts available in modern editions with extensive notes.
