Copious, complete indices to the inscriptions up to 44 BCE offer access to the difficult texts of the early period: Hans Krummrey has compiled the indices for Fasc. 1–2 and 3 and added an index for the inscriptions of the 4^th fascicle. In keeping with the special features of the Republican inscriptions, there is an initial lemmatic word index followed by indices of names, grammar, letter forms, and subject groups.
