After more than one year of good cooperation I took the chance and changed my reference management system from Citavi to Papers. It took a little bit of time (almost four days) to import all my (hopefully) relevant papers into my new system.
After these four days of intense work with it I can already state: Papers2 is just awesome! The import and match functions are really comfortable, highlighting helps a lot retrieving relevant passages and the Magic Manuscript is a great way to cite articles.
Can’t wait to start my work!
