The scope of parliamentary information is vast and is enhanced by communication technologies. Therefore, parliamentary libraries face the challenge of offering services to Members of Parliament (MPs) that are faster, more efficient, and more diverse. In Mexico the Parliamentary Library represents one of the bridges to democracy, a conduit that disseminates information generated by the Mexican Congress. The Internet ensures the public's access to parliamentary information. But this is not enough. The human factor, the librarian's experience and expertise, is fundamental in assisting citizens to retrieve relevant information. This paper highlights the new services provided by the Analysis, Information and Documentation Center (CEDIA) of the Mexican Chamber of Deputies, particularly the products used by the Reference Service to provide information and assistance to the Mexican MP staff as well as to the general public seeking government information.
