How can I find a suitable journal for my paper without using journal selection tools?
My PhD thesis is published and I could publish many papers based on it as per the ideas suggested by my examiners. I created one paper from my thesis and sent it to 5 journals, but it has been rejected. Even Edanz scientific reviewer told me that my paper is original and good to publish in an ISI journal. What to do ? I can't find a suitable journal.
