How Are You Going to Find It?
Information is easier to find than it used to be but there's still more to it than putting a few keywords into Google. There are a range of specialist bibliographic databases each dedicated to a specific subject domain. Thus, in health, there is MEDLINE covering the medical literature, and CINAHL covering the nursing literature. These databases are usually accessible online from University libraries for students. They will only give you access to the abstracts and citation details, but again, your University library can provide access to many journals in electronic and/or paper form.
There is a version of Google designed for scholars, called Google Scholar, which is designed to search the academic literature. Its advantages are that it is very good at finding information because it uses Google's search engine, and it is not limited to one subject area, which can be particularly important for interdisciplinary studies. On the other hand, it is dynamic and opaque, because Google will never tell you exactly what it searches and how it does it, so it is not entirely satisfactory as an academic tool.
A key issue is making sure that you use the right search terms. You need to make sure that you use the same terms as the authors of the papers you wish to find. In some disciplines there is an agreed systematic search terminology. Where this exists, for example, the MESH structured terminology in medicine, you should be using these search terms.
Another traditional way of finding articles to look at those articles cited by the key papers you find. These are by definition, older papers. However, many e-journals, often offer the added facility of articles that have cited the article you are currently reading.
Finally, just because there are computer tools available to help you, never forget that human librarians are trained in search. I guarantee that they will find things that you will not.
