## Research Bibliography

Overview

The purpose of this assignment is to demonstrate competency in using the library for academic research and to compile a list (bibliography) in MLA format of potential sources you might use for your research essay. The research bibliography is a very common academic genre that demonstrates that you have conducted significant and in-depth research on your research question, and therefore are poised to write about it with credibility, accuracy, and precision.

Process

A good guideline for finding sources for an academic research essay is that you should closely evaluate in detail three times as many sources as you will end up using. For instance, for a biology lab report where you are required to use two scientific studies as support, you would closely evaluate six studies on your topic to decide which is the most relevant to your specific experiment. If you were writing an ethics position paper on climate change and you were required to use four peer-reviewed academic journal articles, you would need to closely evaluate twelve articles that address your central idea in order to decide which four would be most effective in your essay. This process of careful evaluation should be applied to any academic context where you are required to use primary and/or secondary sources to address a specific assignment or topic.

You will submit two things for this assignment:

1.
2. A photo of yourself getting a book from the stacks in the library for your essay or using the library’s resources in the library to find sources for your essay. You may use the library at any campus location. Hours for the FSW libraries can be found here (Links to an external site.). If you do not live locally to any of FSW’s four campuses/sites, you may make alternative arrangements with your professor to demonstrate your knowledge and use of the FSW libraries.
3.
4. A list (bibliography) in MLA format of the potential sources for your essay. The list should follow option A or option B below.

Option A                                                                                                  Option B

2 books or ebooks

Articles

2 sources from .gov, .edu, or .org                                                                                                    (government, education, or                                                                                                               organization) websites or                                                                                                                              publications

For this option,

you will include

6potential sources on your

Research Bibliography.

For the research essay, you will

narrow it down to a minimum

of one book, one peer-reviewed

journal article, and one

choice (can be another book,

journal article, website,

personal interview, etc.).

For this option, you will include                                                                                                     6potential sources on your                                                                                                              Research Bibliography. For the                                                                                                       research essay, you will narrow it                                                                                                 down to one peer-reviewed academic                                                                                         journal article, one source from a .gov,                                                                                    .edu, or .org website/publication, and one                                                                                  additional source of your choice (can be                                                                                    another book, journal article, website,                                                                                                 personal interview, etc.).
