Protip. Practice bibliography mining.

If you find a single source on your topic see what sources it cites and read those as well. In a book or article these are usually at the end. If you are starting on Wikipedia for a general overview these are at the bottom where clicking on the footnotes takes you.

one simple trick is to add PDF after your search term. Scientific papers, especially those shared internally within scientific communities will often be published as .pdf

Example: googling "medieval garments" will just display a page after page of un-citated nonsense

Googling "medieval garments pdf" gives you Medieval Garments reconstructed by fransen/nørgaard/østergård. which is one of the best and most useful sources on early medieval clothing.

Google Scholar is better directed towards peer-reviewed literature than a plain google search. There is still a significant amount of legwork to separate the wheat from the chaff and it suffers from the Matthew effect. The algorithm privileges heavily cited papers and just because something is cited a lot does not necessarily mean it's high quality. But its "cited by" is a good quick and dirty way to do bibliography mining.
