We compare traditional and new methods of information search in computer networks. As the result we prove the necessity of considering the quality of information category in the process of information search by students of all forms of education. We give the definitions of “junk information” and information quality. It is necessary to take into account the information quality for intellectualization of information search and eventually for efficacy improvement of information search. One of the main sources of quality information on the Internet is legal electronic libraries. We consider the characteristics of network sources, which contain quality information and allow students to differ legal electronic libraries from unauthorized. As the example we consider several electronic libraries. We recommend to lecturers several tasks, which can be useful for students while learning methods of intellectual information search in electronic educational resources, these tasks are aimed to form competencies of modern educational standards. We conclude it is necessary to pay far more attention to the issue of quality information search on the Internet, than we do today.
