If you're starting with a general topic or concept and want to get an idea of how it has been or is being discussed in philosophy or science and technology studies, these reference sources are good places to start. Oxford Bibliographies, especially, will tell you who the key writers and theorists have been on a specific topic, what the subsets of the topic are, and what publications are available about it. In all of these sources, pay attention to the bibliographies! They are great places to find more specific sources for your project, or at least some places to start.
I also recommend using reference books like encyclopedias, handbooks, and dictionaries that are tailored to your subject. They are a great way to get an overview on your specific paper topic and to familiarize yourself with the terminology before reading research articles. They can also help you decide what to write about, if you have a broad topic of interest but not a specific question about it yet.
