The Ubuntu Academic Lens is an Unity Lens that allows all students, teachers or any other end user to search for scientific information directly from Unity Dash.
It searches the Google Scholar and Pubmed services and it also integrates with the Zotero bibliographic manager.
To install the Unity Academic Lens plugin in your Ubuntu operating system, open a terminal window (hit the CTRL+ALT+T key combination) and paste the following commands (one by one, hitting Enter after each one):
sudo add-apt-repository ppa:markjtully/ppa
sudo apt-get update && sudo apt-get -y install unity-lens-academic unity-lens-zotero
You will need to restart your session after the installation. This Lens is available only for the Ubuntu 12.04 LTS (Precise Pangolin) and Ubuntu 12.10 (Qunatal Quetzal) operating systems.
