Citation Library

Turn DOIs, ISBNs, arXiv ids, PubMed ids or a title into verified references, keep them in named libraries and export BibTeX, RIS, CSL-JSON or formatted lists.

Citation Library resolves an identifier to bibliographic metadata from the source that holds the record: Crossref first and OpenAlex as a fallback for DOIs, Open Library for ISBNs, the arXiv API for arXiv ids, and the NCBI ID converter to turn PubMed ids into DOIs. When only a title is given it returns up to 5 candidate records with a match score and does not fill anything in. A reference is saved only from a record a source returned.

References are kept in named libraries on your account. A library can be read back formatted as APA 7, MLA 9, Chicago author-date or Harvard, or exported as a BibTeX, RIS, CSL-JSON or text file with a download link. The formatting is implemented in this service and covers journal articles, books, book chapters, conference papers and preprints.

Example prompts

Look up the paper with DOI 10.1038/s41586-020-2649-2 and give me the APA and MLA references.
Find the reference for the paper titled "Attention is all you need" and show me the candidates with their match scores.
Add these ISBNs and arXiv ids to my thesis library, then export it as BibTeX.
