OpenScholar is the de facto go to solution for academic sites. Over the past year we saw it being adopted in many Harvard departments and higher ed institutions worldwide.
I'm proud that our work is not just based on open source, but also contributes to it - big time. Case in point, the Biblio module which is responsible for bibliographies and citations since back in Drupal 4.6, and has provided a great solution. It was becoming clear the 4.6 architecture is showing its age, and could use an overhaul.
