Based on data obtained from PubMed and Crossref, Edifix can correct references and insert hyperlinked PMIDs and DOIs.


Edifix can query both PubMed and Crossref and identify articles that match the references you submitted. Careful application of various matching algorithms gives very high confidence in the matches obtained. Once a match is made, Edifix Linking embeds a link to the record corresponding to each matched reference in Crossref and/or PubMed. These active hyperlinks are included in the Edifix output and can be used to provide links to the cited articles. To check the accuracy of a reference in the PubMed or Crossref database, just click on the PMID or DOI link that Edifix has added to the reference.

Note: Because of its more restricted subject coverage (life sciences and biomedicine), PubMed is much less likely than Crossref to produce links to submitted references in other disciplines or subject areas.

A reference that has linked to both PubMed and Crossref may look like this, depending on the chosen editorial style:

1. Molter C, O’Neill J, Yamaguchi Y, Hirase H, Leinekugel X. Rhythmic modulation of θ oscillations supports encoding of spatial and behavioral information in the rat hippocampus. Neuron. 2012;75(5):889-903. PMID:22958828.


Having made a successful match, Edifix can then detect differences between the submitted reference and the information in Crossref and PubMed. Using our experience of these databases, Edifix can identify which errors in the submitted reference can safely be corrected and make those corrections. In some cases, Edifix might instead add a warning about differences between the submitted reference and the corresponding Crossref or PubMed entry.

Importantly, Edifix can also add details required by your selected output style but missing from the submitted references, such as issue numbers, full publication dates (rather than just years) or “full” page ranges (e.g., “1916–1921”) rather than the “abbreviated” ranges used in some reference styles (e.g. “1916–21”). This can save you significant time that would otherwise be spent looking up missing information.

A reference that has been corrected with data from PubMed may look like this:

3. Van Luit JE, Van der Molen MJ. The effectiveness of Korean number naming on insight into numbers in Dutch students with mild intellectual disabilities. Res Dev Disabil. 2011;32(5):1822-1828. PMID:21498042.

PubMed reports that reference 3 "Van Luit, Van der Molen, 2011" was retracted in "Res Dev Disabil. 2011 Nov-Dec;32(6):3018".


When the editorial style No Format is selected, PubMed or Crossref Correction and Linking is limited to linking only; data correction is disabled, as selecting No Format prevents Edifix from making any additional changes to your references.

What if a reference entry already has a DOI?

  • If Edifix is able to parse enough of the reference to find and verify the DOI, the reference is shown in black, the DOI is hyperlinked, and the reference is billable.
  • If Edifix cannot parse enough of the reference to find the DOI, the reference is shown in gray, the DOI is not hyperlinked, and the reference is not billable.
