It is indeed creating lot of confusion among the researchers especially the young ones in selecting impact factor journals. There are journals having different types of impact factors, for example ISI/SCI, SCI expanded, Global impact factor and Universal impact factor. It really creates frustration among the academia. Which impact factor journals are credible and why? Why there is not one type of impact factor? Where the young researchers should go to resolve this issue? All scientists, scholars and researchers are requested to comment and give solid reasons and guidelines please.
