There are three books available as pdfs of this precious collection to me for now. Each sentence given both with interlinear and marginal translations in addition to grammatical explanations and further references to the all time legendary Latin grammar books like that of Allen's.
Caesar's Gallic War (421 pages)
The First Oration of Cicero against Catiline (297 pages)
The Aeneid of Virgil (364 pages)
See attachments to download the files.
Physical hardcover copies of these books can be found here. As we just started providing physical copies of books for Latin.
