Zotero v9.0.6

Zotero is the academic's best friend. It automatically senses research articles in your browser and saves them with one click — complete with metadata, PDFs, and automatic citation generation in Word, Google Docs, and LibreOffice. It's free and open-source, developed by a nonprofit. The 300MB free cloud storage is enough for most, with paid upgrades for heavy users. If you write papers, theses, or anything with citations, Zotero saves hours.
