First, the elements on the History of the Information are discussed, interrelating the description of the Science of the Information, of the Society of the Information and the certified scientific editions. Next, supply and demand and its relations in the market of the scientific knowlegde are presented by showing the particularities of that market with relation to the conventional markets. Finally, it treats the productive chain and databases, specially the Dialog provider and some of its databases by offering quantitative data. The problem is how to demonstrate the contraditory logic in the productive chain of the scientific knowledge, information access was not an spontaneous consequence of the commercial liberalization, but it has created technical and economical gaps for almost totality of the scientific community, intensified and perpetuated by the oligopoly of the big on-line access providers, which gather in themself the biggest private databases. / O trabalho aborda a quest?o das rela??es econ?micas estabelecidas entre as etapas de produ??o, distribui??o e uso da informa??o na cadeia produtiva do conhecimento, dispon?vel nos provedores em linha, para compreender a l?gica econ?mica que sustenta essa ind?stria.Discutem-se primeiramente elementos sobre a Hist?ria da Informa??o, inter-relacionando o hist?rico da Ci?ncia da Informa??o, da Sociedade da Informa??o e das edi??es cient?ficas certificadas. Apresentam-se, em seguida, a oferta, a demanda e suas rela??es no mercado do conhecimento cient?fico, mostrando as particularidades desse mercado com rela??o aos mercados convencionais.Finalmente aborda-se a cadeia produtiva e as bases de dados, particularmente do provedor Dialog e algumas de suas bases de dados, oferecendo dados quantitativos. O problema ? mostrar a l?gica contradit?ria na cadeia produtiva do conhecimento cient?fico, o acesso ? informa??o n?o foi uma conseq??ncia espont?nea da liberaliza??o comercial, mas criou gargalos t?cnicos e econ?micos para quase toda a comunidade cient?fica, recrudescidos e perpetuados pelo oligop?lio dos grandes provedores de acesso em linha, os quais agrupam em si as grandes bases de dados privadas.
