The first source discusses the challenges that Internet users face in selecting relevant information due to the vast quantity and variety of sources available. The lack of effective search tools and limitations of some search engines exacerbate these problems, as they often return a large number of results that lack enough detail to assess relevance or only source a limited number and kind of sites, potentially leading to bias. These restrictions may be hard for novice users to detect.
