HAL does not allow the dissemination of certain document types which, from the point of view of Inria, constitute scientific contributions which it is justifiable to spread according to the model of the free access. HAL-Inria+ was set up in order to allow, since HAL-Inria, to deposit and to disseminate these kind of documents.
It is already possible to deposit :
– Popular scientific articles,
– Documents associated with scientific events (tutorials, poster, preface, short readings, digest conference …)
These documents are not visible of HAL but nevertheless, they are indexed by search engines Google, Google Scholar and OAI harvesters. Such ease of access will enable these publications to reach a wider audience, while being available for longer.
