Docear is a unique solution to academic literature management, i.e. it helps you organizing, creating, and discovering academic literature. Among others, Docear offers a single-section user-interface that allows the most comprehensive organization of your literature. With Docear, you can sort documents into categories; you can sort annotations (comments, bookmarks, and highlighted text from PDFs) into categories; you can sort annotations within PDFs; and you can view multiple annotations of multiple documents, in multiple categories, at once. A ‘literature suite concept‘ that combines several tools in a single application (pdf management, reference management, mind mapping, etc.). This allows you to draft your own papers, assignments, thesis, etc. directly in Docear and copy annotations and references from your collection directly into your draft. A recommender system that helps you to discover new literature.

Zotero is the only software that automatically senses research on the web. Need an article from JSTOR or a preprint from arXiv.org? A news story from the New York Times or a book from a library?

Or create saved searches that automatically fill with relevant materials as you work.

If you decide to sync, you can also always access your research from any web browser. Zotero lets you co-write a paper with a colleague, distribute course materials to students, or build a collaborative bibliography. You can share a Zotero library with as many people you like, at no cost.
