<p>The purposes of this work consisted, first, in analyzing the meanings that 297 undergraduate students of the University of Guadalajara, Mexico, give to scientific information, as well as specifying what they obtain when they search for scientific journals on the Internet. As a conceptual basis, we take The Information and Knowledge Society, to conclude that university students -who answered an open questionnaire with multiple options, analyzed through a thematic content analysis- are more immersed in an informationalist society, rather than in one based on knowledge and judgment, since their meanings about scientific information do not quite agree with their actions, namely, in the selection of scientific journals, which they confuse with diffusion reviews that circulate widely through the Internet.</p>
