How to Generate APA, MLA, Chicago, or Harvard Citations with ZoteroBib

ZoteroBib generates APA, MLA, Chicago, Harvard, and thousands of other citation styles from a URL, ISBN, DOI, title, or manual entry — no account or download required. Paste your source into the single input box, pick the style from the dropdown, and copy or export the finished citation or bibliography. The steps below cover the full workflow, including adding multiple sources and fixing entries the tool can't auto-detect.

Step 1: Add your source

Go to zbib.org. You'll see one input field at the top of the page. You can paste any of the following:

• URL — a webpage, news article, or online journal page
• ISBN — a book's 10- or 13-digit number
• DOI — a journal article's digital object identifier
• Title — for books and articles the tool can look up
• PMID or arXiv ID — for indexed papers

Press Enter or click the add button. ZoteroBib retrieves the metadata automatically and creates a citation entry.

If the tool can't find the source, or you're citing something without an identifier (a print book chapter, a personal interview, a course handout), choose Manual Entry and fill in the fields yourself — author, title, date, publisher, and so on.

Step 2: Choose your citation style

Use the style dropdown above the citation list. Common options:

The dropdown also covers 10,000+ other styles, including specific journal formats. If your instructor or journal requires a named style, search for it directly in the dropdown rather than assuming a generic one matches.

Step 3: Copy or export the citation

Once the entry appears, you have several output options:

• Copy citation — copies the formatted in-text or footnote citation to your clipboard
• Copy bibliography — copies the full reference list entry
• Export — download as RTF, HTML, or BibTeX, or copy in a format your word processor accepts

For a single source, copying the bibliography entry is usually enough. For a paper, keep adding sources (Step 4) and export the whole list at once.

Step 4: Add multiple sources and build a bibliography

ZoteroBib keeps every source you add in a running list on the same page. Add each book, article, or webpage the same way — paste, confirm, repeat. The bibliography updates automatically and stays in the style you selected.

When you're done:

1. Check the order — most styles alphabetize by author's last name; some (like Chicago notes-bibliography) may differ.
2. Click Copy bibliography or Export to move the full list into your document.
3. Paste into your word processor and apply the hanging indent your style requires (ZoteroBib's export usually preserves formatting, but verify after pasting).

Common issues and fixes

The metadata is wrong or incomplete. Auto-retrieval depends on the source page having clean metadata. Click the entry to edit any field manually — author names, dates, and titles are the usual culprits.

The style looks slightly off. Citation styles get updated (APA 7 replaced APA 6, for example). Confirm the edition in the dropdown matches what your instructor asked for.

You need in-text citations, not just a reference list. Use the copy-citation option for the parenthetical or footnote form, and the bibliography option for the reference list. They're separate outputs.

Corporate or anonymous authors. Manual entry handles these; put the organization name in the author field and leave the individual-author fields blank.

What ZoteroBib does not do

It doesn't store your sources between sessions or sync across devices — that's what the full Zotero desktop app is for. It also doesn't insert citations directly into a Word or Google Docs file the way a word-processor plugin does. ZoteroBib is a quick, browser-based generator: you paste, format, copy, and paste into your document yourself. For a one-off paper or a handful of sources, that's usually faster than installing anything.
