DOI to BibTeX Converter
Paste a DOI and get a complete BibTeX entry — author, title, journal, volume, year, and pages filled in automatically from Crossref's official metadata. Copy it straight into your .bib file. Free, no sign-up.
How it works
- The DOI is looked up on Crossref, the official DOI registration agency — so the metadata is the publisher's own, not scraped.
- The work type is mapped to the closest BibTeX entry type: @article, @book, @incollection, @inproceedings, or @misc.
- BibTeX-special characters ({ } % &) are escaped, and the citation key follows the author + year + first title word convention (smith2024quantum).
Frequently Asked Questions
- How do I convert a DOI to BibTeX?
- Paste the DOI (for example 10.1038/nphys1170, or the full https://doi.org/... link) into the box and click Convert. The tool looks up the official metadata on Crossref and builds a complete BibTeX entry — entry type, citation key, author, title, journal, year, volume, pages, and DOI — ready to paste into your .bib file.
- Where does the metadata come from?
- From Crossref, the official DOI registration agency for scholarly publishing. The lookup uses the publisher's own deposited metadata, so authors, titles, volumes, and pages are exact rather than scraped or guessed.
- Which BibTeX entry types are generated?
- The Crossref work type is mapped to the closest BibTeX type: journal articles become @article, books and monographs become @book, book chapters become @incollection, conference papers become @inproceedings, and anything else falls back to @misc.
- What does the ‘protect capitalized words’ checkbox do?
- BibTeX styles often lowercase titles, which mangles proper nouns and acronyms — DNA becomes dna. Enabling the checkbox wraps every capitalized word of the title in braces ({DNA}, {Bayesian}), which tells BibTeX to keep its exact casing. It is a common convention, but optional.
- How is the citation key generated?
- Using the most common convention: first author's surname + year + first significant title word, all lowercase and stripped to ASCII — for example smith2024quantum. You can rename the key to anything you like before pasting it into your .bib file.
- Why does my DOI fail to convert?
- The two usual causes are a typo (a DOI always starts with 10. followed by a registrant code and suffix) or a DOI registered with an agency other than Crossref — for example DataCite DOIs for some datasets — which this lookup cannot see. Check the DOI on doi.org, and remove any trailing punctuation that came along when copying.
