When doing research you are often building on the work of others and will sometimes take an idea, fact or quotation from someone else’s work such as a book or article. If you are including such ideas/facts/quotations on your poster, you must cite your sources to give credit to other researchers and writers and so others can trace your research or retrieve the source materia. The same is true for other kinds of sources such as pictures or other graphics that may be incorporated into the design of your poster.
If you have a handout to accompany your poster, you may list your references on that. If not, you should list them in small type at the bottom of the poster.
Different meeting sponsors/organizations may have differing styles for formatting citations. Use the style required in the abstract/poster guidelines or your research advisor. This site from Bedford St. Martins gives examples of citations in the fields of the Humanities (MLA style), Social Sciences (APA), History (Chicago Style), and the Sciences (Council of Science Editors). These examples are not exhaustive and you should consult the appropriate style manual in the library. The “Vancouver” style was developed by the US National Library of Medicine and adopted by the International Committee of Medical Journal Editors. This NLM ICMJE page gives example of 41 different kinds of sources and should be considered the authoritative style for medical sciences.
Posters presented at meetings include both items that were only presented in this way or those which were followed by a publication. If you do follow a poster with a publication, cite that subsequent work on your CV rather than the meeting poster.
Regardless of the style you follow, elements for the citation will be the same: Author name(s), title of the poster, title of the conference/meeting, date, location. The conference may also have a descriptive “name” as well as a title.
Here are the rules for formulating a poster citation in the “Vancouver”/ NLM / ICMJE style:
