Google is a good starting point for searches for info, especially if you filter out unwanted terms in an advanced search and are discerning about what you’re looking for. DuckDuckGo is a very good alternative, it doesn’t track your searches like Google, so will often suggest different and better results. Google Scholar is an academic search engine. It lists how often the article has been found to be cited, and tells you where it was cited, giving you an idea of the relative importance. You can search in a similar way in the college library, and use the Google search bar there, follow the “Where can I get this” link and you’ll often get the full articles to download. Checking the author’s bibliographies can get you some more good results. Use “create alert” link at the bottom of Google scholar and you’ll get notified of related searches through email.
