Frequently asked questions
What is a DOI?
A Digital Object Identifier (DOI) is a permanent, unique string assigned to scholarly works. It always starts with 10. (e.g. 10.1038/nature12373) and reliably resolves to the correct paper even if the publisher's URL changes.
Is DOIFinder free to use?
Yes. Searching, metadata retrieval, citation generation and all exports (BibTeX, RIS, EndNote XML) are completely free. You can use every core tool without an account — signing in is optional and only needed to sync your library, save literature reviews and follow papers across devices.
Where does the data come from?
We query Crossref first — the world's largest DOI registry — and fall back to OpenAlex for broader coverage of preprints and older literature. Both are free, open scholarly databases.
Can I search without a DOI?
Absolutely. Use the DOI Finder to search by paper title, research keywords or author name, then generate a citation from the results.
Are the citations accurate?
Citations are built from verified publisher metadata, minimising typos. You should still confirm them against your institution's or journal's specific style guidelines before submitting.
