DOI Citation Generator

Turn a DOI and the article details into a ready-to-paste citation in seven styles.

Reference details

Any form works: 10.xxxx/…, doi:10.xxxx/… or a doi.org link.
Authors
    A range (583–589) or an article number (e0123456).

    Everything you type stays in your browser. Nothing is uploaded.

    FAQ

    Can this tool fill in the details from the DOI for me?

    No — it formats what you type and never looks anything up online. You'll find every field on the article's page or on the first page of the PDF.

    Which citation styles can I generate?

    APA 7, MLA 9, Chicago (author–date), Harvard (Cite Them Right), IEEE and Vancouver, plus a BibTeX entry for LaTeX. Journal names print exactly as you type them — IEEE and Vancouver officially prefer abbreviated journal titles, so shorten the name yourself if your venue requires it.

    What happens with a long author list?

    Each style applies its own rule: APA lists up to 20 authors and collapses 21 or more to the first 19, an ellipsis and the final author; MLA switches to “et al.” from three authors, Harvard from four, IEEE and Vancouver from seven, and Chicago lists up to ten.

    What can I paste into the DOI field?

    Any common form: 10.xxxx/…, doi:10.xxxx/… or a https://doi.org/… link. It's cleaned and lowercased before it goes into the citation, and anything that still isn't a valid DOI is flagged so a typo never reaches your bibliography.

    The DOI Citation Generator is a free online tool designed to build ready-to-paste journal article citations in seven different styles live in your browser. Instead of relying on external database queries, the tool formats the reference details and Digital Object Identifier (DOI) that you manually type or paste into the form, updating the citation in real time as you fill in the fields.

    How the Generator Processes Inputs

    The tool relies on manual input to construct citations, ensuring that the user maintains complete control over the metadata. Under the Reference details heading, the input form accepts the following fields:

    • DOI: Accepts any common format, including a raw DOI starting with 10., a prefix format like doi:10., or a full https://doi.org/ link.
    • Article title
    • Authors: Multiple authors can be added or removed. For each author, the user provides a Family name and Given name(s).
    • Year: Must be entered as four digits (e.g., 2024).
    • Journal: Journal names are printed exactly as typed.
    • Volume
    • Issue
    • Pages: Accepts a page range (e.g., 583–589) or an article number (e.g., e0123456).
    • Citation style: A selection of one of the seven supported styles.

    Users can click "Fill example" to load sample data, which displays the confirmation message "Example loaded — replace it with your own details.". Clicking "Clear" resets the form and displays the confirmation "Cleared.".

    Real-Time Output and Status Messages

    The generated citation is displayed under the Citation heading. The tool provides immediate feedback based on the state of the input fields:

    • When the form is completely empty, the output area displays: Your citation builds here as you type — start with the title and the year..
    • If both the title and year fields are missing, the status message reads: Waiting for a title and a year..
    • If only the title is missing, the status message reads: Waiting for the title..
    • If only the year is missing, the status message reads: Waiting for the year..
    • Once the minimum required fields are provided, the status message updates to: Citation ready..

    Validation Rules and Edge Cases

    To prevent formatting errors from reaching a bibliography, the tool applies specific validation rules to the DOI and Year fields:

    DOI Cleaning and Validation

    The tool automatically cleans and lowercases the DOI input before placing it into the citation. If the input does not conform to a valid DOI structure, it is flagged with the error message: "This doesn't look like a DOI — it starts with 10. and has a slash, like 10.1038/xyz123.".

    Year Validation

    The year must be entered as a four-digit number. If this rule is violated, the tool displays the error message: "Enter the year as four digits, like 2024.".

    Journal Name Formatting

    Because journal names are printed exactly as typed, users must manually enter abbreviated journal titles if their target venue requires them. This is particularly relevant for IEEE and Vancouver styles, which officially prefer abbreviated journal titles.

    Author Truncation Rules Across Styles

    Each academic style guide has distinct rules for handling publications with long author lists. The DOI Citation Generator automatically applies these specific truncation rules to the generated citation:

    Citation Style Maximum Authors Displayed Truncation Behavior
    APA 7 Up to 20 authors For 21 or more authors, the list collapses to show the first 19 authors, followed by an ellipsis (...), and then the final author.
    MLA 9 Up to 2 authors Switches to "et al." when there are three or more authors.
    Harvard (Cite Them Right) Up to 3 authors Switches to "et al." when there are four or more authors.
    IEEE Up to 6 authors Switches to "et al." when there are seven or more authors.
    Vancouver Up to 6 authors Switches to "et al." when there are seven or more authors.
    Chicago (author–date) Up to 10 authors Lists up to ten authors in the reference list.

    Local Browser-Based Privacy

    All processing happens entirely within the user's web browser. Everything typed into the tool stays on the local device, and nothing is uploaded to an external server.

    BibTeX Integration for LaTeX Users

    For researchers working in LaTeX, the tool generates a clean BibTeX entry alongside standard text-based styles. This allows users to quickly copy structured bibliographic data directly into their .bib files without manual coding or formatting.

    Frequently Asked Questions

    Can this tool fill in the details from the DOI for me?

    No — it formats what you type and never looks anything up online. You'll find every field on the article's page or on the first page of the PDF. This manual approach avoids the incorrect or incomplete metadata often pulled by automated database tools.

    Which citation styles can I generate?

    APA 7, MLA 9, Chicago (author–date), Harvard (Cite Them Right), IEEE and Vancouver, plus a BibTeX entry for LaTeX. Journal names print exactly as you type them — IEEE and Vancouver officially prefer abbreviated journal titles, so shorten the name yourself if your venue requires it.
