At the library and on the Internet, browse for a topic you want to learn more about. If you have a short list of ideas, do a quick check of reference works to get overviews of topics. You can begin with a general encyclopedia or a specialized reference work that focuses on a specific area, such as psychology (16c). You can also use Wikipedia as a starting point: look at entries that relate to your topic, especially noting the sources they cite. While you should never rely on Wikipedia alone, it is a highly accessible way to begin research.
