Citation Management Tools can help you collect, organize, and reuse sources that you find in your research. They are especially helpful for creating lists of references in the style you need and for organizing PDFs of articles or reports.
Zotero is a citation manager to help you collect, manage, and cite your references.
Zotero allows you to attach PDFs, notes and images to your citations, organize them into collections for different projects, and create bibliographies.

EndNote X7 is a comprehensive version of the bibliographic software program, with advanced features to facilitate the maintenance and storage of bibliographic citations, web resources, and images.
