I'm trying to develop a stronger sense of what/how Latin vocabulary was used at different points in the history of the language. In looking around Google and archive.org, I've found dictionaries from, say, the 19th century that contain only words Cicero used (e.g. the Lexicon Ciceronianum, in three volumes (1, 2, and 3)), but are there any modern dictionaries or dictionary-like resources that either
a) contain only Latin from certain ages (preferably Golden, Silver, or both),
b) classify entries by age, or
c) include information on age as part of a word's entry?
My main current aim is to develop a sense of the corpus of Golden Age vocabulary and what words meant at that time, as distinct from words that entered the language later or that changed their meaning over time.
But I can imagine all sorts of other ways in which such a dictionary/resource might be helpful.
