Before the internet, the first thing people would do would be go to the library and look into an encyclopedia (usually Britannica, but it could be another one).
Nowadays you got google, and usually the first hit happens to be wikipedia (which generally is good unless it’s been a vandalized page - remember nearly anyone can edit a wikipedia article). Due to that fact, most academic authorities now refuse to accept wikipedia as a citation for research. Usually, though, the wikipedia article will contain external links or references to print material at the end and those are good to follow.
Anyway, there’s your starting point:
