One identifier per line. We’ll resolve it and return a BibTeX entry. Nothing is stored.
0 / 2,000 characters
Each resolved identifier produces a BibTeX entry. The entry type (e.g. @article, @book, @misc for preprints) is inferred from the resolved metadata. The citation key is auto-generated from the first author, year, and a short identifier suffix.

Output
@article{watanabe2023s41586,
author = {Watanabe, ...},
title = {Title of the paper},
journal = {Nature},
year = {2023},
volume = {615},
pages = {123--130},
doi = {10.1038/s41586-023-05881-4}
}Book chapters, conference papers, theses, and preprints each get the appropriate entry type automatically. Fields vary depending on the publication type and what metadata is available from the source database. Common fields include author, title, journal, year, volume, pages, and doi.
BibTeX is a reference file format used alongside LaTeX to manage citations and bibliographies. A .bib file contains one or more entries, each describing a publication - its authors, title, journal, year, and identifiers. When you cite a source in a LaTeX document, BibTeX pulls the metadata from the .bib file and formats it according to the selected bibliography style.
BibTeX is the lingua franca of academic bibliographies in STEM. Most reference managers - including Zotero, Mendeley, JabRef, and BibDesk - can import and export .bib files. Even if you don’t use LaTeX, BibTeX is a convenient interchange format for moving references between tools.
See the BibTeX entry in our glossary.
Enter any of the following scholarly identifiers and the tool will resolve the full bibliographic metadata and generate a BibTeX entry.

A .bib file is supported by virtually every tool in the academic writing ecosystem:
.bib file and cite it with \cite{key}..bib files directly..bib file editor.Yes. Enter one identifier per line. The tool will resolve each one and return all BibTeX entries in a single block, ready to copy or download as a .bib file.
The entry type is inferred from the resolved metadata. @article is used for journal articles, @book for books, @inproceedings for conference papers, and so on. If the type cannot be determined, @misc is used as a fallback.
Check that you have entered a valid DOI (starting with 10.), PMID, PMCID, ISBN, arXiv ID, ISSN, or ADS bibcode. The tool resolves identifiers against CrossRef, PubMed, PubMed Central, OpenLibrary, arXiv, and NASA ADS. If the upstream database is temporarily unavailable, try again in a moment.
Yes. No account required. Nothing you enter is stored.
