The SciELO - Scientific Electronic Library Online Project (www.scielo.br) is becoming a common model for the cooperative publishing of scientific and technical electronic journals in Latin American and Caribbean countries. Since its launch in March 1997, promoted by a partnership pilot project led by FAPESP (www.fapesp.br), BIREME (www.bireme.br) and a group of Brazilian scientific editors, the SciELO Model was already adopted by Chile, and there are several ongoing initiatives that lead us to expect that five more countries will adopt SciELO during 1999. By the end of the year 2000, it is expected that at least 100 journals will be published under the SciELO Model throughout Latin America and the Caribbean. The SciELO Model aims at the operation of electronic libraries of scientific journals on the Internet. It comprises two major components: the methodology for electronic publishing, and the Internet site that actually operates the journal collections.
