Sonnenwald and Wildemuth’s 2001 study could be categorized as information seeking by role. The authors investigated the information behavior of students. They developed a new technique of mapping information seekers' information source horizon. This will be a useful technique when investigating movie watching behavior. Combined with semi-structured interviews and a survey, this approach provided more in-depth analysis, as well as data triangulation, when looking at the information horizons of 11 undergraduate students of a lower socio-economic status. The authors based this technique on Sonnenwald's theoretical idea of information horizons. They explain, "This theoretical framework suggests that within a context and situation is an 'information horizon' in which we can act" (Sonnenwald & Wildemuth, 2001, p. 68). The researchers asked the students to talk about their information behavior and then asked them to draw a map placing the information sources they mentioned. The students placed the resources and people they used for information seeking in reference to themselves. As they drew the students talked about their preferences for the sources as well as links between them. Of particular interest is that 8 out of the 11 students listed the Internet as an information source they accessed first.
