Scholarly resources may not be apparent if you simply "Google." You can increase the likelihood that an authoritative resource appears at the top of your results by limiting your search by filetype (filetype:pdf) or domain (site:.gov or site:.edu or site:.org). Alternatively, you can begin your search at Google Scholar.
Internet Archive Scholar is a good alternative to Google Scholar. For scientific literature, there is Semantic Scholar.
You might experiment using an artificial intelligence (AI) research assistant, such as Elicit, ResearchRabbit, or Perplexity. You'll have to "sign up," but they are free.
