Why create a network of architecture, art, design and urbanism libraries in Argentina and Latin America? Would it not have been better to join one of the existing networks in developed countries, which are more efficient? But do we have the same needs, requests and resources? The Vitruvio network originated in Argentina about 10 years ago and has spread, unplanned, to other countries in this region such as Peru, Uruguay and Ecuador, establishing its objectives to suit the libraries co-operating in the project. Sustainable products and services have been developed, in line with the needs of the region, using a minimum of financial, technological and human resources, and highlighting the profession’s determination and hard work.
