Any royalties but they charge the readers a substantial amount of money per paper in my field (computer science), IEEE, ACM, Springer, Elsevier are some known journals/publications and none of them pay authors.
I am a brand new PhD student so please bear that I am missing here with me if there is something obvious. I became told through my consultant that to graduate i have to publish in IEEE or ACM. He failed to recommend, and I also don’t know of any reputed journal in my field, that either pays royalties to writers or permits free usage of visitors. I will be forced to create my documents at IEEE or ACM if I would like to graduate in order to find work afterward.
