I presented a poster 3 years ago in a small conference and added the poster to my CV and ResearchGate profile. At the request of the conference organisers, I also wrote a short article describing the poster that was published in the conference proceedings one year ago.
I guess it would be unethical to add both the poster and the article to my CV and ResearchGate profile, but which one should I use? Is it better to use the article in the proceedings? And in that case, should I consider it as a poster, an article or a conference paper?
