"If you need to keep track of your research--whatever it may be--Zotero is the tool to use! Drop in a ISBN, DOI, PMID, or arXiv, from whatever you're reading and it populates the item type, author, abstract, and numerous other fields. I use LibreOffice, and the plugin works perfectly; I drop a quote and Zotero generates a footnote/endnote, and bibliography. Add something and the note numbers change to match. I barely scratch the surface of what Zotero is capable of, but I find it a joy to use. Less formatting, more typing. Terrific add-on!"
