What this tool helps you do

Paste a DOI (e.g. 10.1038/nature12373), an ISBN, or a URL and the tool fetches publication metadata from CrossRef and OpenLibrary. You can also fill in the fields by hand. The output covers the six most-requested academic styles — APA 7th, MLA 9th, Chicago (notes-bibliography), IEEE, plus BibTeX and RIS for reference managers (Zotero, Mendeley, EndNote).

  • You need a correctly formatted reference for a journal article, book, or website.
  • You want to convert a DOI, ISBN, or URL into citation-ready publication details.
  • You need BibTeX or RIS output for a reference manager such as Zotero, Mendeley, or EndNote.

How it works

  1. 1Paste a DOI, ISBN, or URL in the lookup field, or enter the publication details manually.
  2. 2Select the source type: journal article, book, or website.
  3. 3Add available fields such as title, authors, year, publisher or journal, pages, DOI, and URL.
  4. 4Generate formatted citations in APA 7, MLA 9, Chicago, IEEE, BibTeX, and RIS.

Use cases

  • Format journal article references for essays, research papers, and literature reviews.
  • Create book and website citations from ISBNs, URLs, or manually entered metadata.
  • Export references in BibTeX or RIS for academic reference management.

Examples

1. Format a renewable-energy journal article

University student

Background

A student is preparing a research paper about renewable energy adoption and has complete publication details for a journal article.

Problem

The article must be cited consistently in several academic formats.

How to use

Select Journal Article, enter the title, authors, year, journal, volume, issue, pages, and DOI, then generate the citations.

Source type: Journal Article; authors: Smith, John and Doe, Jane; year: 2024; journal: Journal of Energy Policy; volume: 42; issue: 3; pages: 123-145; DOI: 10.1234/example.2024.042

Outcome

The article is formatted in APA 7, MLA 9, Chicago, IEEE, BibTeX, and RIS.

2. Look up an article from its DOI

Researcher

Background

A researcher has a DOI but does not want to enter the article's title, authors, and publication details manually.

Problem

The available source identifier needs to become a complete reference in multiple styles.

How to use

Paste 10.1038/nature12373 into the lookup field and generate the citation output.
