The Internet is a network that enables individuals worldwide to comfortably and instantly retrieve an unprecedented amount of information on almost any topic. Individuals commonly use the Internet for formal research activities in educational contexts (e.g., Salmerón, Strømsø, Kammerer, Stadtler, & van den Broek, in press); however, they also use it to make informed decisions and to seek knowledge and advice about personal, medical, environmental, political, and financial issues (Estabrook, Witt, & Rainie, 2007; Smith, 2009). In this chapter, we focus on the use of multiple online sources to seek information in such informal or non-academic contexts.
