This is a very intresting question. Justa s a suggetsion, do you think, you should follow first Scopus and the WoS address? I think it is a great start, and not a bad option...
University journal can be upgraded to Indexed Journal and there is no. problem. This work may be done by university publication section. One can take the help of university Library.
Mª Angeles Zorrilla Lopez-Perea Thank you very much for your suggestion. Yes SCOPUS and WoS are the most popular and getting into their list is very much interesting. I feel the budding journals today should focus on them.
