Evaluate Information

The timeliness of the information.

• When was the information published or posted?

• [Web sites]: Do all links work?

The importance of the information for your needs.

• Does the information relate to your topic or answer your question?
• Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?
• Have you looked at a variety of sources before determining this is one you will use?

The source of the information.

• Can you verify any of the information in another source or from personal knowledge?
• Does the language or tone seem unbiased and free of emotion?
• Are there spelling, grammatical, or other typographical errors?

The reason the information exists.

• Does the point of view appear objective and impartial?
• Are there political, ideological, cultural, religious, institutional, or personal biases?
• [Web sites]: What types of colors, graphics, audio, video, text are used? What do these elements convey? How effectively does the site or page convey the intended message? 
• [Web sites]: Do the graphics provide useful additional information or serve an important function or are they merely aesthetically pleasing?
