Publishing journal articles based on dissertation My dissertation is drafted in a paper format which consists of three papers that I am planning to publish in future. Can I submit the manuscript to journals in 'as is' condition or I will have to draft new manuscripts based on the old manuscripts.

Please advise.

Thank you.
It is often possible to republish your dissertation as articles but it depends on the publishers and it sometimes requires permission.

Journal publishers will generally not publish work that is published elsewhere but dissertations are a common exception. This page run by the MIT libraries lists many science and engineering publishers and their rules about publishing articles that first appeared in dissertations. For other publishers, you'll need to check websites or ask journal staff or editor.
