I put this in the Suggestion forum for web archaeologists to find, centuries from now. Sometimes I think that the folks that got upset with the Catholic church (begin with a 'p') view latin as an unholy road to a truly bad ending.
More seriously:
Sabatier's Bibliorum Sacrorum Latinae Versiones Antiquae Seu Vetus Italica (3 vols)
It's originally 1743, re-published more recently in 1976. An improved version of Sabatier was begun by Dold in 1949, but has spotty coverage, though arguable as to 'which'.
For interested Logosians:
In Logos: https://www.logos.com/product/125665/the-old-latin-and-the-itala which is older, cheaper, and a good discussion
Or not in Logos:
Metzger's Early Versions of the New Testament (an excellent volume).
The old latin sort of forms the third leg of the greek-syriac-latin comparison. Augustine went nutty criticizing it (being multiple versions), some say due to its raw nature (gentlemen latinists would mightily frown at it). I think it's most interesting with its similarity to the so-called Western text. And the variation between the African, and European versions.
