This document shows our concern about how libraries can participate in the increasing world of networks and cybercitizenship. The Library of Congress of Chile is exploring these possibilities and shares how this experience of adding value to Congress and the roles of congress persons could be extended to other libraries. We have identified three ways in which a library can approach cybersocial networks. Firstly, as a sponsor and co-creator, providing technological platforms and human capabilities so citizens can learn to participate in cybernets. Secondly, as a citizen trendwatcher, that identifies social conversations, particularly those emerging and not published yet in papers or books. Lastly, as a promoter of emerging collectives that shape the national community, around issues of social political interest in Congress. With a strong commitment to promoting digital culture, the Library's web catalyzes all our digital services, eliciting a very high response from the public. We share the path taken, the drivers and steps followed in this exploration. © 2008, SAGE Publications. All rights reserved.
