PMID to citation generator
Paste one or more PubMed IDs, pick a style and get a reference list you can copy straight into your paper. The details come from each paper's own record, and the formatting from the official style files.
Your reference list
How it works
Paste your PMIDs and pick a style
One per line, up to 10 at a time. A bare number, a PMID: prefix or a full PubMed link all work. DOIs work here too. Choose Vancouver, AMA, APA or one of six more styles.
We look each one up
Each PMID is looked up in OpenAlex, an open catalogue of scholarly works that holds the records of articles indexed in PubMed, together with their DOIs.
Copy the list
The references come back formatted and in the order the style asks for. Copy them with the formatting, such as italic journal names, kept.
A worked example
Paste PMID 31978945, the first report of the novel coronavirus in the New England Journal of Medicine, choose Vancouver, and the reference reads:
31978945
1. Zhu N, Zhang D, Wang W, Li X, Yang B, Song J, et al. A Novel Coronavirus from Patients with Pneumonia in China, 2019. New England Journal of Medicine. 2020 Jan 24;382(8):727–33. doi:10.1056/nejmoa2001017
Vancouver lists the first six authors and then et al., gives the full date of an online first article, and shortens the page range. In AMA the same paper lists the first three authors and then et al., gives only the year and keeps the full page range; in APA every author up to twenty is named.
What each result means
- Found
- The PMID resolved and the reference is built from its record. Check it once, as you would any reference, before you hand in.
- No record found
- OpenAlex has no record for this PMID. It may have a typo, or the article may be too new to be indexed yet. If the article has a DOI, paste the DOI instead.
- This DOI is registered with an agency we cannot read yet
- You pasted a DOI that belongs to a registration agency other than Crossref or DataCite, so we cannot read its record yet. Use the article's PMID, or write that reference by hand.
- Not a PMID or DOI
- The line does not look like a PubMed ID or a DOI. A PMID is a number of up to nine digits, often written as PMID: 12345678.
- Daily limit reached
- The daily limit for the free tools has been reached. It resets at midnight UTC.
- Could not look this up right now
- A lookup or the formatter did not answer in time. Nothing is wrong with your PMID: try again in a minute.
What a PMID is
A PMID, or PubMed identifier, is the number PubMed gives every record it holds. It never changes, so it is a reliable way to point at one article, and many medical journals and guidelines cite it alongside the DOI.
You find it on the article's PubMed page, under the title, and often in the citation tools of journal websites. It is a plain number, without the 10. that starts a DOI.
Which style should I use?
Use the style your course, department or journal names. In medicine, nursing and the health sciences that is most often Vancouver or AMA; psychology and many social sciences use APA.
Vancouver numbers each source in the order you first cite it and keeps the reference short. AMA also numbers sources and is the house style of JAMA and many other medical journals. Nature's style and ACS are used by their own journals and in chemistry.
In-text citations
A reference list is half of the job. Each source also needs a citation in your text where you use it: a number in square brackets or superscript in Vancouver and AMA, an author and year in APA.
Number your sources in the order you first cite them when you use a numbered style, and keep the same number each time you cite that source again.
Check before you hand in
A reference is only as good as the record behind it. Records are usually right, but a title can carry odd capitals, journal names are sometimes given in full where your style wants the abbreviation, and very new articles may lack a volume or page range.
Read each reference once against the article itself. If your style asks for abbreviated journal names, as Vancouver and AMA usually do, check each one against the abbreviation the journal uses.
Questions
Is this PMID to citation generator free?
Yes. You can format 10 PMIDs at a time and 30 a day without an account. The limit resets at midnight UTC.
Which citation styles can I choose?
APA 7th edition, MLA 9th edition, Chicago author-date, Harvard, IEEE, Vancouver, AMA, Nature and ACS.
Where do the details come from?
From OpenAlex, an open catalogue of scholarly works that holds PubMed's records. The formatting uses the official style files of the Citation Style Language project.
Do you keep the PMIDs I paste?
No. The PMIDs are sent to OpenAlex to look them up, and are not saved or linked to you. DOIs you paste here go to OpenAlex and doi.org in the same way. We count how many lookups each visitor makes in a day, using a key that cannot be turned back into an address and that changes whenever our service restarts.
Can I paste DOIs and PMIDs together?
Yes. Each line is read on its own, so a list can mix PMIDs and DOIs.
Why are the journal names not abbreviated?
The record gives the journal's full name. Vancouver and AMA often use the abbreviated form, so check your style's rule and shorten the names if it asks for that.
My PMID says no record found.
Very new articles can take a little while to reach the catalogue we look them up in. If the article has a DOI, paste that instead: the DOI to citation generator reads it straight away.
