I am contemplating submitting a journal paper to either Elsevier (Journal of Power Sources) or IEEE (Trans. Power Electronics). Their impact factors are very similar. While I am pretty clear on the parameters of IEEE, Elsevier has two very different options which I am not sure about. My questions are :
1) Elsevier has two options: open access or subscription. While open access costs 3300$, subscription-based submission is free. That's quite a difference.
2) What is the difference in copyright rules after the publication
I would appreciate comments from anyone that has published an Elsevier journal before, or contemplated it and has a clear idea.
