As a usual practice, full manuscripts for oral presentation are published online as part of the proceedings journal/book of abstracts. Can we still submit the same paper to are reputable journal for publication?
Hi Angelo. Yes you can still publish your work in another journal even after presenting it in a conference. However kindly write a formal letter to the conference organizers that you are doing this as there are times where they might have already endorsed your paper for publication in their conference proceedings (which in other countries are also journals). There are also some cases where the organizers decide to write a special publication out of a conference so it is best to ask their advise too.
Sometimes journal publishers have such rules that you need to extend your full paper published in the conference books/CDs. This extension sometimes need to be at least 30-40%. And you also need to indicate that presentation in the text. Its better to check the publishers rules and contact them. Otherwise plagiarism programs can detect your both publications.
I think you can publish the article if you do some corrections (title, abstract, and content) to be as new article as a whole. Thanks for your question
