How DOI to BibTeX lookup works
Every published paper, book chapter, or dataset with a DOI has a record in CrossRef, the official DOI registration agency for academic content. This tool sends your DOI to CrossRef's public API, parses the response, and formats it into a BibTeX entry , with the correct entry type (article, inproceedings, book, or incollection), full author list, journal or book title, volume, issue, pages, and DOI URL all populated automatically.
For papers in IEEE journals, conference proceedings, or arXiv , all of which use DOIs, this is usually faster than copying fields by hand. If a DOI returns incomplete metadata (some older or obscure publishers don't register every field), fall back to our citation generator and fill in the missing fields manually.
For researchers writing papers
If you're writing a paper with 30+ references, doing this DOI by DOI is slow. Underleaf imports a batch of DOIs into your bibliography in one step, deduplicates against your existing .bib file, and inserts the correct \cite{key} commands as you write. The DOI converter on this page is great for one-off lookups; the app handles the rest of the workflow.
