Vancouver Personal Communication Citation Generator

Citing a personal communication (private correspondence (email, letter, or memo)) under the National Library of Medicine / ICMJE (Vancouver Style) framework requires combining Vancouver's punctuation hierarchy with the specific metadata of the source. To construct a compliant entry, researchers must collect the sender/communicator name, exact date of the communication, recipient name, and medium (e.g., personal communication, email, or archival letter). In the body of your paper, Vancouver utilizes parenthetical or superscript Arabic numbers assigned sequentially as sources appear in the clinical text, which links directly to an entry organized in sequential numerical order of appearance in the manuscript body.

When formatting a personal communication in Vancouver, pay close attention to contributor names and capitalization. Specifically, Vancouver enforces surname followed by up to two initials without spaces or periods (e.g., Pasteur L, Koch R), listing the first 6 authors before adding "et al.", and applies sentence case without italics or quotes for both book and article titles, paired with NLM-abbreviated journal titles without periods. Vancouver style uses compressed page ranges (e.g., 245–9 instead of 245–249) and places bracketed medium designators like [Internet] directly after the container title. Furthermore, if your personal communication does not display an individual creator, the rule is straightforward: always identify the sender of the correspondence by their initials and surname.

For digital and online personal communication references, Vancouver stipulates adding "[Internet]" after the title/container, "[cited YYYY Mon DD]" after the publication date, and "Available from: URL" at the end. If the letter is housed in a public historical archive, cite it as an archival document in your bibliography rather than a private communication. Using the client-side Vancouver Personal Communication generator below, you can automatically parse URLs, DOIs, or ISBNs and apply these exact Citation Style Language (CSL) rules locally in your browser with zero server tracking.
