Science communication is essential for the development of science. In addition, scientific libraries constitute a reliable and stable means of communication of scientific knowledge for Master's students and young researchers (PhD students), because they not only hold printed editions, but also manage electronic editions. Likewise, the evaluation of Internet resources is a specific challenge to supplement those derived from traditional printed sources. In this context, existing knowledge is published and can be read by scientists, alongside the appearance of new ideas which can be developed and developed, leading to new publications, which can be read again by others. other researchers, …. To have a good efficiency of the process of the development of science, we address this course to all the students, but preferentially to those who start their higher studies, and, who will have to collect scientific information, process it and integrate it with research results in order to write scientific articles, publications, book chapters, a dissertation or a thesis on a local, regional or international scale. The objective of this course is to make the student aware of certain practices that allow him to write a scientific document oriented towards engineering with clarity and methodology.
