Enter a DOI, PubMed ID, PMCID, arXiv ID, ISBN, ISSN, or ADS bibcode. Verify the publication details and retrieve the full bibliographic metadata — title, authors, journal, year, and more.
We’ll resolve this identifier and show you the full bibliographic metadata. Nothing is stored.
Entering a DOI such as 10.1234/jneurosci.2025.04123 returns the full bibliographic record.

Identifiers
10.1234/jneurosci.2025.0412339012345A Digital Object Identifier (DOI) is a permanent link to a published work. Every modern journal article, preprint, data set, and increasingly every book chapter has one. A DOI always starts with 10. followed by a registrant code, a slash, and a suffix - for example, 10.1038/s41586-023-05881-4. Unlike URLs, DOIs never break: even if a publisher moves their website, the DOI always resolves to the current location of the work.
Looking up a DOI gives you the full bibliographic record - who wrote it, where it was published, when, and what identifiers it carries. This is useful when you have a DOI but need to verify the paper’s details before citing it, or when you want to check whether a DOI is valid.
You can enter any scholarly identifier - not just DOIs. The tool resolves it against the appropriate database (CrossRef for DOIs, PubMed for PMIDs, arXiv for preprints, OpenLibrary for ISBNs, NASA ADS for bibcodes) and returns the full metadata. If you’re not sure what type of identifier you have, try the Identifier Detector first.
The lookup returns all available bibliographic fields for the resolved publication:
Fields vary depending on the publication type and what metadata the source database provides. Books may include publisher and edition; preprints may lack volume and pages.
The identifier may be malformed, or the upstream database may be temporarily unavailable. Check that you entered the identifier correctly - DOIs must start with 10., PMIDs are numeric, PMCIDs start with PMC. If the identifier is valid but the lookup fails, try again in a moment.
No - this tool shows you the raw metadata fields, not a formatted citation. If you want a citation in APA, Vancouver, or any other style, use the main Scholar Sidekick formatter.
Yes. No account required. Nothing you enter is stored.
Once you have verified the metadata, format the citation in any style, export to BibTeX or RIS, or check its retraction status and open access availability.
