There are several different reference styles, such as APA,
MLA, and Turabian to name a few.
The format you select may depend on your professor's instructions or your own
preference. Regardless of which method you use, citations in your footnotes
and bibliography should contain the same basic information:
- the author's name,
- the name of the book or journal,
- the publisher,
- the date and city of publication, and
- the page number of the quotation.
Citations within the text of your paper (parenthetical
citations) are shorter versions of the full reference. Their formats also vary
depending on the style but will always include the author's name, and either
or both the year of publication and page number.
Examples of various in-text citation styles
are listed below. For more detailed information and examples, explore the resources
listed in the Links section.

APA
APA style uses the author-date format to cite references within the text:
- As Brown (1995) suggests, . . .
- According to recent studies (vonYahn, 2004), . . .
- Experts agree that this method is no longer effective (Xu, 1998; Hardy, 1999; Brown, 2002).

MLA
MLA style uses only the author's name to cite
paraphrased or summarized references within the text. When directly quoting
the author, use the author-page number format.
- Experts agree that this method is no longer effective (Xu; Hardy; Brown).
- Keeping in mind that LBSure is "the most rapidly appreciating product on the market" (vonYahn 75), UniCom should consider purchasing the system this fiscal year.

Websites
Additional information is necessary when referencing
a website. Although there is yet to be a consensus among experts on the proper
format, some basic guidelines are discussed below.
A good rule of thumb is
to inclue as much information as possible (remember, the main purpose in providing
a reference is to assist the reader in finding your source). Elements you should
include are:
- the page title (found either in the text of the page or in your browser's title bar),
- the URL or address,
- the author (often listed at the bottom of the page with copyright info), and
- the date you accessed, downloaded, or printed the web page.
Watch out for:
- Frames. If the website
uses frames, be sure to obtain the actual URL of the page from the page
properties rather than just the top-level frame.
- Missing author info.
If the author's name is not listed, use the organization or company name
instead.
- Moved or removed pages.
Pages and documents are often reorganized or removed from websites without
notice. You should always print or save a copy of the page to avoid losing
access to the information.
Several guidelines and
style sheets for citing electronic sources are available. Refer to the Resources
section for a brief listing.
