DOI finder
Paste a paper title, a reference line, or an author and year. The finder searches Crossref and DataCite and returns the DOI with a copyable link.
How to use it
- Paste the title of the paper, or the whole reference line from a bibliography.
- Press Find. The best matches appear with their authors, venue and year.
- Copy the DOI, open it, or click Cite to get BibTeX and formatted references for it.
Why you'd use it
A DOI is the one identifier that survives a journal moving its website or a preprint becoming a paper. Reference managers, submission systems and many journals ask for it, and a reference without one is the first thing a copy editor sends back.
Searching for a DOI by hand means opening the publisher page and hunting for it. This page asks the two registries that assign DOIs, Crossref for journals and conference proceedings and DataCite for arXiv and datasets, and shows what they know.
FAQ
How do I find the DOI of an article?
Paste its title into the box above and press Find. The DOI is shown under the matching title. If you only have a citation, paste the whole line; the search ignores the parts it cannot match.
Why does my paper have no DOI?
Not everything gets one. Many workshop papers, older conference papers and theses were never registered. arXiv preprints do have DOIs (10.48550/arXiv followed by the arXiv id), and this finder returns those through DataCite.
Where does the data come from?
Crossref, the registry used by almost every publisher, and DataCite, which registers arXiv, Zenodo and dataset DOIs. Both are queried live from your browser; nothing is stored here.
Is the first result always the right paper?
Usually, but not always. Check the authors and year before copying. A short or generic title can match several papers, and a preprint and its published version are two different records.
Can I get a citation from the DOI?
Yes. Every result has a Cite button that opens the BibTeX generator with the DOI filled in, and from there APA, MLA, IEEE and ACM.
