Zotero

Zotero is a free (open-source) citation software that allows, among other things, the management of citation data, inserting them into text in MS Word or LibreOffice, and formatting them according to the requirements of a specific citation style or journal publisher.

It enables storing and managing documents obtained from the university’s subscribed databases, repositories, websites, as well as directly from a computer, flash drive, etc. You can also add personal notes, keywords, highlight important sections of the text in colour, and copy them along with the already inserted citation.

You can find detailed tutorials at Zotero.org.
