What sciences help scientists extract information from historical sources?

There are quite a few sciences that help scientists obtain information from historical sources, but archeology occupies the first place among them, since it is in the process of excavation that household items, weapons, houses, and sometimes even whole cities are found, according to which scientists restore the history of mankind. In the decoding and reconstruction of historical sources, computer programs, for example, computer modeling, are actively used. Such sciences as genealogy, heraldry, historical grammar, sigillography, historical chronology also help to obtain information.
