There are three important goals to keep in mind when researching a source. A researching is trying to find the topic the source is discussing, how it is being discussed, and keep it in context by learning what the different positions of the topic are.
It is important to remember that a research paper will come from the culmination of the research on a number of different sources. One will add their own voice to many others that he/she has researched and learned. This notion that a research paper is only a small part of the research is called the iceberg of research.
When discovering sources, one should mentally divide them into two categories: primary and secondary sources. Primary sources are sources that one will analyze and probably reference directly in the research paper. Secondary sources offer perspective on the subject that give the researcher knowledge, context, and perspective on the topic. They will give the researcher a better understanding of the topic, like a lens to look at the primary sources through.
The best way to find primary sources is places where documents and written sources are archived. The library is the most basic way, however places such as museums and city halls can prove to provide effective primary sources.
Secondary sources are found primarily in the reference section of the library (where encyclopedias and guides can be found) and in archives such as online databases.
When researching on databases, the web, or a library catalog, it is helpful to make a list of search terms for each. These should be specific, not general and inclusive. If a person is researching social media, it may be best to use the word "Facebook" because sources that mentioning Facebook are probably about social media. Searching with the words "social media" would yield many extraneous sources because sources that have the words "social" and "media" could be focussing on many things other than social media.
Evaluating sources effectively is essential for a credible research paper. The source that requires the most skepticism is a website. First one should evaluate the author and source. Personal websites are unlikely to be credible, it is best to find a source from a credible author on the website of a credible institution.
Library and database sources should be evaluated with rhetorical analysis. One should try to find the purpose, focus, and audience of the source. An opinion based book by an unqualified author would not constitute a credible source. Other sources may be well written with legitimate facts and citations in them, but written for the purpose of entertainment, such as a book by a political pundit.
Field research should be analyzed for the requirements of a legitimate study. If the study only looks at a portion of the data or conducted the research without using reliable methods (such as a large sample size, random samples, and diverse samples), it is not credible.
Lastly, it is a good idea to make an annotated bibliography as research progresses. This way a researcher can list his/her sources with notes on each source and how it could be used in the research paper.
This is the process and methods that "Envision in Depth" details about how to effectively find and evaluate research sources.
