Citation: why and how?
In academic research it’s considered crucial to acknowledge your sources for several reasons:
- it allows your reader to find your sources for additional information
- it bolsters your credibility in arguing (so that you have some support for your facts and claims)
- it gives credit to the work of others, distinguishing what is your original idea from which of your ideas rest on or respond to the previous work of others (allowing you to enter into a dialogue with other scholars, the heart of academic work)
- it prevents you from the unfortunate consequences of charges of plagiarism
There are many systems by which this citing of sources is done, but for any citation system this involves two tasks:
- you must tag each quotation or paraphrase or summary from your original source to identify where you found that info
- you must include complete bibliographic info for that source in a list at the end of the paper
Remember that in any of the following cases you must provide proper documentation:
- You used a direct quotation from one of your sources
- You mentioned some fact not considered to be common knowledge that you obtained from one of your sources
- You refer to some idea or theory that you learned about in one of your sources
Disciplines in the humanities often use MLA documentation rules (so-called because the guidelines come from the Modern Language Association). Click here for a handout from BCC’s Writing Center about MLA documentation. If you need more information, see the Purdue OWL’s section on MLA documentation, or visit the Writing Center (or me!)
Every place in your text that uses information from a source (whether it’s a quotation, summary, or paraphrase) MUST INCLUDE an in-text citation that identifies the source you used.
In MLA format, this in-text citation is usually either the last name of the author, or if a source has no author, the title of the article or webpage. On eother common situation: you have an article written by Joe Brown, a journalist who quotes Mary Green, an expert on global warming. That case is handled in this way:
Mary Green, president of the National Council of Blah-Blah, has pointed out theĀ <a signal phrase that gives the author of the quote> “Some clever quote that makes an important point” <the quote you extracted> (qtd. in Brown). <qtd. in stands for quoted in–gives the author or the article, as it’s listed in your Works Cited page>.
