For an overview of the ways to cite electronic information in text in APA style, see the Purdue OWL, which provides an overview of the basic in text citation formats.
The APA Style website provides an overview of information regarding citations in text of electronic material on the APA Frequently Asked Questions page, including e-mail communications, entire websites, web pages with no authors, and website material with no author, no year, and no page numbers.
Information about citing e-mail messages, websites with no author, entire websites, and more can be found in the APA Style Frequently Asked Questions page under the References section.
The BGSU library has an APA Style PDF handout that you can refer to for APA style examples.
The Purdue OWL has a detailed page with examples of electronic resources in APA format.
The general rule for citing Web pages in APA format is to include as much information as possible. If there is no date available, use (n.d.), which stands for "no date". If the website URL you are citing runs onto the next line, be sure to break the address after a "/" (http:// is an exception). More information about electronic sources is available on the Purdue OWL site.
