Thank you very much for sharing many links to get further insight into the issue.

Hello Deepak Kumar Behera

I can see that journals often need money to support their work but I have often found journals with no publication fees. That is satisfactory for me because I am not in a hurry and can wait until I receive the returned review(s) but I realise it is more of a problem for newer researchers or those who need it to fulfil the requirements for their degree and need to get it sooner than what I would.

Excellent reply. I am impressed. Thanks for your insightful response.
