Descreve as opções tecnológicas e metodológicas para atingir a interoperabilidade no acesso a recursos informacionais eletrônicos, disponíveis na Internet, no âmbito do projeto da Biblioteca Digital Brasileira em Ciência e Tecnologia, desenvolvido pelo Instituto Brasileiro de Informação em Ciência e Tecnologia (IBICT). Destaca o impacto da Internet sobre as formas de publicação e comunicação em C&T e sobre os sistemas de informação e bibliotecas. São explicitados os objetivos do projeto da BDB de fomentar mecanismos de publicação pela comunidade brasileira de C&T, de textos completos diretamente na Internet, sob a forma teses, artigos de periódicos, trabalhos em congressos, literatura "cinzenta", ampliando sua visibilidade e acessibilidade nacional e internacional, e também de possibilitar a interoperabilidade entre estes recursos informacionais brasileiros em C&T, heterogêneos e distribuídos, através de acesso unificado via um portal, sem a necessidade de o usuário navegar e consultar cada recurso individualmente.This paper describes technological and methodological options to achieve interoperability in accessing electronic information resources, available in Internet, in the scope of Brazilian Digital Library in Science and Technology Project - BDL, developed by Brazilian Institute for Scientific and Technical Information - IBICT. It stresses the impact of the Web on publishing and communication in science and technology and also on information systems and libraries. The work stresses the two main objectives of BDL project: promoting electronic publishing of different full text materials - theses, journal articles, papers in events, "grey" literature - by Brazilian scientific community, so amplifying their nationally and internationally visibility; and achieving, through a gateway, interoperability among those heterogeneous electronic information resources available in the Web, thus avoiding a user to navigate and query those resources one by one separately.

This paper discusses the field of tension that has arisen from the emergence of a digital culture in public schools that participate in digital inclusion projects. Based on the theoretical and epistemological assumptions of cognitive ecologies and structural coupling, we discuss the production of meanings about the virtual-digital as a necessary path for the opening of new possibilities regarding the use of digital technologies in education. We performed an exploratory workshop with teachers of a statewide network of public education, involving local cartography supported by digital technologies, locative media and mixed reality. The workshop was designed to lead participants to an informational and aesthetic experience for the production of meanings about the virtual-digital on the basis of a dual - technological and symbolical - appropriation using technologies such as QRCode markers, digital media, geolocation and publishing in a blog. The teachers showed an understanding of the virtual-digital as a technology that can expand physical experience, the experience of time and protagonism among teachers and students. We conclude by discussing the "being part of" a digital culture on the basis of the demand for a reconfiguration of pedagogical practices and their cognitive regimes, regimes of authority and the very notion of sociability in relation to the educational process.
