Have been less than thirty years since a group of graduate students and computer scientists working on a federal contract performed the first successful connection between two computers located at remote sites. This group known as the NWG Network Working Group, comprised of highly creative geniuses who as soon as they began meeting started talking about things like intellectual graphics, cooperating processes, automation questions, email, and many other interesting possibilities 1 . In 1968, the group's task was to design NWG's first computer network, in October 1969, the first data exchange occurred and by the end of that year a network of four computers was in operation. Since the invention of the telephone in 1876 no other technology has revolutionized the field of communications over the computer network. The number of people who have made great contributions to the creation and development of the Internet are many, the computer network a much more complex than the phone is the result of people of many nationalities and cultures. However, remember that some years later in 19732 two computer scientists Robert Kahn and Vinton Cerft created a more sophisticated communication program called Transmission Control Protocol - Internet Protocol TCP / IP which is still in force in the Internet today.

As international contribution, we have an excellent essay by fellow Mexican Guillermo Hector Alfaro, who proposes an interesting analysis of the relationship between history and library science and urges us to take up the study of the past of our discipline in order to establish it in a field of knowledge thoroughly scientific.These articles examine both the purely practical and those that require theoretical analysis for the growth and development of our subject area. Finally, we urge all the library community to participate and return to the Library Journal, your contributions, in particular, articles, essays and technical reports.
