Please advise resources where you can search for dissertations using keywords. We need sites where you can choose the type of scientific work (article, dissertation, etc.). Thank you!
You can use ResearchGate to search for specific types of research papers; other popular resources include Google Scholar (scholar.google.com) for finding research papers and ProQuest (proquest.com) for dissertations and theses.
In my opinion, connected papers is a great tool for locating references around specific keyterms. It provides summaries of the articles spotted, the number of citations and references used by each one so as the researcher can evaluate the article prior to full-text reading. it also generates graphs illustrating for the connection(s) between the articles which it enlists. it shows the overall period in which all the articles suggested were published. so you know that you have read all that was published between 2010 and 2023 for instance.
