the problem of restricted access can easily be solved using existing infrastructures and with a small additional effort on behalf of the authors or their librarians - Pandelis
If you are Web savvy, it is a 'small effort' to self-archive your work in a space you control. But not everyone can manage that. And then, feedback, reviews and collaboration also in a space you control is no 'small effort'. Linking to and from specific parts of other research is not trivial when reports and results are missing fine-grained open identifiers. Maintaining your reputation and tracking the effect of your work (so that other researchers and institutions take you seriously) is no 'small effort'. Searchability and guaranteeing long-term persistence is no 'small effort'. There's still a way to go on both the infrastructure and cultural fronts here.
The (Social) Web has most of the pieces. They just need putting together.
That's what we're working towards with #LinkedResearch.
