What is "qiqqa"

Qiqqa (pronounced "Quicker") is a freeware and freemium reference management software that allows researchers to work with thousands of PDFs. It combines PDF reference management tools, a citation manager and a mind map brainstorming tool. It integrates with Microsoft Word XP, 2003, 2007 and 2010 and BibTeX/ LaTeX to automatically produce citations and bibliographies in thousands of styles. Researchers and research groups can store, synchronize and collaborate on their PDF documents, annotations, tags and comments using the internet cloud-based Qiqqa Web Libraries.
