Digital materials used in teaching and learning are called learning objects (LO). Traditionally, LOs were developed for use as support materials for teacher. However, they can be used by students or whoever is interested in learning something. LOs can be found in repositories and also on the Web, in teachers and institutions sites. In spite of that, they are not easily found. Repositories address few knowledge fields and few languages. Search engines return a large amount of information that makes it difficult for users to identify relevant LOs to meet their goals. In this context, this paper proposes a new mechanism for LOs retrieval, based on Web 2.0 principles. Among the options for Web 2.0 applications, the model of social bookmarking called our attention because it provides facilities to store links to LOs, and also to share and classify these links. Moreover, unlike what happens with the repositories, in these tools, any user can post new links, without restrictions. The prototype of this tool was called VITAE. VITAE provides links to LOs, in a way that people can store, organize and share them with others.
