Reference & Citation Managers
Reference management software tracks citations, generates formatted bibliographies, and integrates with word processors during manuscript writing. This sub-cluster covers the major tools researchers actually use — Zotero (free, open-source, browser-integrated), Mendeley (Elsevier-owned, with a social/discovery layer), EndNote (long-established, institution-licensed, strong in law and medicine), and Papers — along with the underlying interchange formats (RIS, BibTeX) that let libraries move between them. Pages here are comparative and task-focused: which tool fits a given workflow, how to migrate a library between tools, and how to troubleshoot the export/import step that most often breaks.
Guides
Migrating a Mendeley Library to Zotero
Zotero imports a Mendeley library online, keeping folders, tags, notes, files and PDF annotations. Sync fully first, and copy group-library items into your personal library before starting.
Fixing Undefined Citations and BibTeX Errors
Citations showing as [?] usually means the compile sequence, not a broken bibliography: LaTeX writes .aux, BibTeX writes .bbl, and only the third pass substitutes the labels.
Editing a CSL Citation Style for a Journal That Has None
When a journal has no CSL style, start from the closest one in the repository rather than a blank file — and check first whether a dependent style pointing at an existing one is all you need.
Reference Managers for macOS Researchers: What Actually Breaks by Platform
What genuinely differs on macOS: Zotero’s reduced-feature Connector on older macOS, EndNote’s install-order and quit-every-Office-app repair rule, Mendeley Cite’s Word-only scope, and Bookends as the one Mac-and-iOS-only holdout.
Unlinking Zotero Citations and Removing Field Codes
The Unlink Citations / Convert to Plain Text step before journal submission: what field codes are, how Word and LibreOffice differ from Google Docs, and the irreversible-step save-a-copy discipline.
Customizing Zotero Citations: Locators, Prefixes, and Omitting the Author
How to add a locator (page number), a prefix or suffix, or omit the author for a narrative citation on a single Zotero reference, and what survives a citation-style change.
Citations in Quarto, R Markdown, and Pandoc
Quarto, R Markdown, and plain Pandoc all format citations through the same shared engine — Pandoc’s citeproc. This guide covers the bibliography and csl YAML fields, [@key] citation syntax, where the three tools genuinely diverge, and the fixes for the most common broken-citation problems.
ZotFile and Automatic PDF File Management in Zotero
ZotFile’s own project page says it’s no longer actively maintained, and Zotero 7+ added a real customizable file-renaming system of its own. This guide walks through what each actually does, what native Zotero still can’t do, and how to decide whether to install ZotFile at all.
Backing Up and Restoring a Zotero Library
Zotero’s sync keeps devices current, but the server only holds the most recent version — not a backup history. This guide covers what’s actually in the data directory (zotero.sqlite plus the storage folder), the safe way to back it up, why syncing the live data directory through Dropbox or OneDrive risks corruption, and the exact steps to restore or move a library to a new computer.
EndNote Alternatives for Researchers
A migration guide for researchers leaving EndNote: what Zotero, Mendeley, and JabRef cost, how to export via RIS or XML, and exactly what formatting, attachments, and group structure don’t survive the move.
Citing Sources in PowerPoint with Zotero
Zotero has no official PowerPoint plugin. Here are the four real ways to get a correctly formatted citation onto a slide, and what each one costs you in setup time and risk.
Exporting a Zotero Library into EndNote
Two ways to migrate a Zotero library into EndNote — RIS export for references only, and EndNote XML export to bring attached PDFs along — plus the item-type and field losses the RIS interchange format is known to introduce.
Finding and Merging Duplicates in Zotero
Zotero’s Duplicate Items pane groups records by title, DOI/ISBN, or a loose year+author fallback, but it can’t merge items of different types (a preprint vs. its published version), and it misses pairs with mismatched DOIs or titles entirely. Here is the matching logic, the exact failure cases, and a manual reconciliation pass for a merged systematic-review library.
Reference Managers That Work Inside Microsoft Word
Zotero, Mendeley Cite, EndNote, and RefWorks all integrate with Word directly — and so does Word’s own built-in citation tool. Here is what actually works, and where each one’s real limits sit.
Producing an Annotated Bibliography From Zotero
Zotero has no one-click annotated-bibliography feature. This guide covers the Extra/Abstract field mechanism the built-in annotated-bibliography styles actually read, how to install one from the Style Repository, and the full path from a collection to a finished document.
Citation Managers That Work With Google Docs
Only Paperpile and Zotero were built for Google Docs natively. Here is how EndNote, Mendeley, and RefWorks actually compare on real Google Docs support, not marketing claims.
Paperpile in Word, Google Docs, and the Browser: How the Citations Actually Work
How Paperpile’s Word add-in, Google Docs plugin, and Chrome extension actually differ under the hood, and how a Google-Docs-first lab can still submit a clean manuscript to a Word-only journal.
Taking and Exporting Notes in Zotero
How Zotero’s native note system works: standalone vs. child notes, the rich-text note editor, annotation-to-note extraction, and exporting notes as Markdown, HTML, or via Zotero RDF.
Better BibTeX for Zotero: Setup and Citation Keys
How to install the Better BibTeX plugin, configure and pin its citation-key formula, and set up Auto-Export so your .bib file updates itself as your Zotero library changes.
Changing and Updating the Citation Style in Zotero
Zotero separates two settings that are easy to confuse: the style attached to one Word/LibreOffice/Google Docs document, and the styles installed in your Zotero library. This guide covers both, plus installing new CSL styles and keeping them current.
EndNote Cite While You Write Explained: What CWYW Actually Stores in Your Document
Cite While You Write inserts a hidden field code, not plain text, at every citation. Here’s what that data actually holds and why it matters for co-authors and journal submission.

Cite While You Write is not a separate download – it installs with EndNote Desktop. This page covers the install order that breaks it, the Windows COM add-in and Disabled Items rungs, and the macOS Customizer, stated per platform and dated.
Using Zotero with Google Docs: The Word Round-Trip and Shared-Document Failures
Zotero stores Google Docs citations as links, not field codes. That single fact explains the dead citations after a .docx download, the collaborator who silently unlinks half a bibliography, and the wrong-Google-account permission error.
