A DOI (Digital Object Identifier) is a unique, permanent identifier assigned to scholarly articles, books, datasets, and other digital content. It looks like 10.1038/s41586-024-07421-0 and resolves to the publisher's page for that work. DOIs are managed by the International DOI Foundation and are the standard way to identify academic publications.

How do I convert a DOI to APA format?

Paste your DOI into PapersFlow's DOI converter, select 'APA 7th Edition', and click convert. The tool pulls metadata from CrossRef and formats it according to APA 7th edition rules, including proper author formatting, italicization, DOI as URL, and hanging indent formatting.

Can I convert multiple DOIs at once?

Yes. Paste multiple DOIs separated by newlines and PapersFlow converts them all in a batch. You can export the results as a formatted bibliography, a BibTeX .bib file, or add them all to your PapersFlow library.

Is the DOI converter free?

Yes, completely free with no ads and no sign-up required. You can convert unlimited DOIs. Creating a free PapersFlow account lets you save converted citations to your library for later use.

How do I get a BibTeX entry from a DOI?

Paste your DOI into the converter and select 'BibTeX' as the output format. You'll get a complete @article{} entry ready to paste into your .bib file for LaTeX/Overleaf. The entry includes all standard fields: author, title, journal, volume, number, pages, year, and doi.

What if a DOI doesn't resolve?

Some DOIs are newly registered and take time to appear in CrossRef. If resolution fails, try pasting the full DOI URL (https://doi.org/...) or the paper title. PapersFlow will search OpenAlex and PubMed as fallback sources.

Can I convert a DOI to MLA or Chicago format?

Yes. PapersFlow supports APA, MLA, Chicago (both author-date and notes-bibliography), Harvard, IEEE, Vancouver, and 10,000+ other citation styles. Select your preferred style from the dropdown after pasting your DOI.

How accurate are the citations?

Citations are generated from authoritative metadata sources (CrossRef, OpenAlex, PubMed) and formatted using the official Citation Style Language (CSL) processors. Accuracy matches or exceeds other citation generators. Always verify critical submissions against your style guide.
