Recover the version actually cited
Start from DOI or title, compare records, open the manuscript or publication and record its version.
Documents to open in this workflow
This order suggests a starting point; revisit a step if identifiers, dates or versions disagree. Access and reuse terms depend on each service.
Crossref Metadata Search
Search metadata deposited with Crossref by DOI, title, author or citation.
What to record
Exact DOI, title, authors, publisher, date and declared update links.
Source-specific check
Open the publisher page; bibliographic metadata alone cannot verify a scientific finding.
Open source portalHAL
Find published or unpublished research outputs, metadata records and deposited files in a multidisciplinary open archive.
What to record
HAL identifier, version, document type, available DOI, file and licence.
Source-specific check
Cite the version read; metadata and deposited manuscript may carry different dates.
Open source portalEurope PMC
Search life-sciences literature, preprints and links to full text, data and related resources.
What to record
Identifier, record source, DOI, type, version and text link.
Source-specific check
Compare identifiers before counting two records as independent studies.
Open source portal
Matching condition
Link DOI or local identifier to each manuscript, edition and update notice.
If results disagree
If passages differ, cite the read version and record corrections; do not silently replace earlier quotations.

Frequently asked questions
What link should be checked before matching results?
Link DOI or local identifier to each manuscript, edition and update notice.
What if sources appear to contradict each other?
If passages differ, cite the read version and record corrections; do not silently replace earlier quotations.
Do the listed portals provide independent confirmation?
Not necessarily. Identify the producer and underlying document. Two interfaces distributing one item can check transcription but do not establish a fact independently twice.
