If you are not sure what your topic is all about, check it out in a dictionary or encyclopedia. For a recent overview of your topic try a handbook or a yearbook. They can have all kinds of facts, figures and precise information.
Books are a good starting point.
Use the Word search in the library's catalogue. You can search on words like phenomenology . Looking through journals in the hope of finding something relevant is time-consuming. It is better to use the databases or printed indexes to find journal articles on your topic. When you are searching, near enough may not be good enough.
