Docear

While not many people have to deal with loads upon loads of academic research papers, those who are given the task are often faced with tedious organizational work. With Docear, those days are in the past. This comprehensive software features an easy-to-use single-part user interface for organizing any sort of scholarly research documents. Papers can be sorted into various categories with the click of a button. Even the annotations on these documents can be sorted easily. Once a user gets the hang of Docear, it's possible to view multiple annotations of many documents at the same time. Thanks to the software's "literature suite" design, multiple tools are combined in a single application. For example, within Docear, one can utilize reference management, PDF management and mind mapping without having to open more application on the machine. Docear also comes equipped with a unique document recommendation system that will automatically suggest new literature based upon what's already stored in the software's database, making additional research on a subject easier than ever.
