Instead of managing the research sources manually, once can use Zotero. Zotero is the only research tool that automatically senses content in the web browser, allowing the researcher to add it to his/her personal library with a single click. Zotero is a free, easy-to-use tool that can be used for collecting, organising, citing, and sharing the research sources. Zotero collects all research resources in a single, searchable interface. The researcher can add PDFs, images, audio and video files, snapshots of web pages, and really anything else. Zotero automatically indexes the full-text content of the research library, enabling the researcher to find exactly what s/he is looking for with just a few keystrokes. It can highly improve the process of managing the research sources and consequently the process of conducting research.
