• Content: What is the author's bias? Who was the information written for?
• Currency: What is the publication date?  When was the website last updated? Does this matter for your topic?
• Validity: Is the information accurate or valid?  Are there references to other works that support the information?
• Publisher: Do they have a good reputation?

From the University College Policies on Academic Integrity:

"Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner, serving as a basic guiding principle for all academic activity at Penn State. All members of the University community are expected to act in accordance with this principle. Consistent with this expectation, the University's Code of Conduct states that all students should act with personal integrity; respect other students' dignity, rights and property; and help create and maintain an environment in which all can succeed through the fruits of their efforts.

"Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others."
