This chapter reflects objective and subjective principles to organize and disseminate information. It presents the human condition in the dynamic of searching and using information by making explicit the informational need of the user with learning theories, information organization, and user studies as subsidies. This is done in order to increase the development of cognitive trajectories to search, select, and use information, bearing in mind the permanent process of modifiability to face new environments. Finally, the text focuses on the social and economic development promoted by the science and technology advances, pointing out the social gap that has emerged from this reality.

The theoretical and experimental studies from the 1950’s aim to solve the issues of and information recording and retrieval, made clear by Saracevic:

“[…] the nature of information, the knowledge structure, and its records (including Bibliometrics), the use and the users, leading to studies of human behavior with information; the interaction man-computer, with emphasis on the human side of the equation; relevance, utility, obsolescence and other attributes of the information use along with methods and measures to assess the information retrieval systems; economy, impact and value of the information, among others”. (Saracevic, 1996)

Within these studies, Mooers (1951 apud Saracevic, 1996), brought up the expression “Information Retrieval,” and he sought answers to the following questions:
