"Qiqqa is awesome. I spent a bit of time trying to decide which reference software to use before beginning my phd this fall. I had tried citeulike for my master's dissertation and explored endnote, mendeley and others, but none of them did everything I wanted. Qiqqa is far superior to anything else out there. Thank you so much for making it!" - Jess
