I don't have any concrete tips.

We have very little written material surviving from Rome, at least from the period before a codex (book) was invented, which was more durable that a scroll. Often, we only know of one source describing important events, and when it comes to political struggles and civil wars, the perspective of the defeated party often did not survive. The punishment of damnatio memoriae was practised and even among the early emperors, Caligula and Nero were subject to a form thereof. (This library in Herculaneum was buried 11 years after Nero's death.) I would be surprised if everything in the scrolls perfectly aligned with the record that survived for 2000 years and that was filtered by both random chance and political/religious censorship. Even Christians later destroyed some pagan texts.

BTW personally, I would love for some textbook of Etruscan to emerge from there. This was once again a language whose teaching was banned in Rome.
