Beginning Your Library Research - Using Databases
Most libraries subscribe to a wide variety of information services that lead researchers to appropriate databases for their subjects. As you search databases, remember that you have to try a variety of keywords. Also, make sure you know your research goals: are you searching for full texts of articles? do your sources need to be peer reviewed? Understanding what you are looking for can help you to hone your search.
For his English composition research assignment, suppose David is interested in writing about the process of fracking and how it affects the environment. He is using the General OneFile database to find information. David wants to find full articles online so that he doesn't have to go to the library.
Review the information David has entered into his search. Then, answer the question that follows.
Which of the following are true about David's search? Check all that apply.
1. He's excluded information about pollution from fracking in his search.
2. He's only getting evaluated and vetted information about fracking and pollution.
3. He's broadened his search to information on either fracking or pollution.
4. He's narrowed his search to those references containing both fracking and pollution.
5. He's narrowed his search to full texts of documents.
