Choosing a topic - where do you begin?
Many students choose a topic that they already know something about and explore new research in that area. Whatever you choose, make sure you are interested in the topic! If you don't have an idea yet, browsing through the library's book collection in biology will present you with a broad variety of subjects. You might also want to scan issues of the magazines Discover, New Scientist, BBC Knowledge, or Science to read about topics in the recent news.
Too big or too little?
A quick way to get a feel for how well your area has been researched is to run a search in Google Scholar. If only 10 hits are returned you'll know you have to expand your topic or change your topic. There just isn't enough information. On the other hand, if you get 10,000 hits you'll know you have to narrow down your topic. Google Scholar also has a link at the top of the results list to limit results by date.
If a book or article you want is not available, use Interlibrary Loan (ILL). The Library can order books and articles from other libraries. This process takes few days but is completely free for DelVal students, faculty, and staff.
If you have answered "yes" to these five questions you have probably located a scientific article.
Research articles are also often known as scientific or peer-reviewed articles. If the article is NOT written by the person or group who did the research, it is NOT a peer-reviewed or scientific article. Research articles are important for knowing what new discoveries have been made. This is why it is important to use recent articles, since they will be the first things published on a new scientific development.
Here's a quick overview of how to identify these journal articles:
