Scholarly Editions of Greek and Latin Texts
Whenever possible, you should use scholarly editions of classical texts. A scholarly edition of a text typically will present and discuss variant versions; provide historical, cultural and linguistic context; and delineate the history of scholarly approaches to that text.

Bi-lingual Editions
