Check PDF Bibliography — Find Unverified References
Check the references in a PDF bibliography against academic databases so weak or missing metadata is visible before you cite or import the records.

What to do next
How it works
Step 1
Upload your PDF bibliography
Drop a PDF that contains a references section. CiteMe extracts the bibliography server-side and discards the file.
Step 2
Match against academic databases
Each parsed reference is checked against academic databases including OpenAlex, CrossRef, Semantic Scholar, PubMed, and other sources so canonical metadata can replace weak parses.
Step 3
Review the verification report
See which references are verified, enriched, or not matched, then copy, export, or save the corrected records when useful.
