In most STEM fields, and in most of the quantitative social sciences, the format of articles (or conference papers, especially in computer science) is the most important way to find scholarly information about a research topic. Mathematics and Statistics still use books about as equally as articles, and there are several social science fields that will also use books extensively.
I have highlighted a few books and article databases of possible interest below. There may be other places besides these that are better for you. If you need help, visit the "Getting reference assistance" tab to find support.
