Zotero — The Complete Guide: Free Reference Management for Theses and Research
Zotero is a free, open-source tool for managing sources: papers, books, standards, reports and websites. It keeps them in an organised library, lets you read and annotate the PDFs, and inserts citations and a bibliography into your document in any style — without typing a single reference by hand.

- One-click saving — the browser extension recognises a paper on ScienceDirect, IEEE, ASCE or Google Scholar and saves it with all details and the PDF.
- Add by identifier — paste a DOI or ISBN and the details fill in automatically.
- Built-in PDF reader — highlights and notes that are saved and searchable.
- Organisation — collections by project or chapter, tags and full-text search.
- Citing — a plugin for Word and LibreOffice that inserts references and builds the bibliography; hundreds of styles such as APA, IEEE and Harvard.
Theses and LaTeX
If you write in LaTeX or LyX, the Better BibTeX extension exports the library to a .bib file that updates automatically. The same reference library then serves both a paper in Word and a thesis in LaTeX.
Standards and engineering documents
You can add items of type “standard” or “report” manually — for example a national standard, a Eurocode or a lab report — and attach the file. That way all the literature for a project lives in one place.
Costs
The software is completely free. Syncing between computers is included; Zotero's cloud file storage is free up to 300 MB and paid beyond that — but you can sync files through WebDAV or keep them local.
