How do I find a journal's type (e.g. SCI, EI)? I'm filling out a form with information about my publications, and one of the fields is "Type of Journal." I'm not sure what this means, except that SCI and EI are possible values. I'm guessing the former refers to Science Citation Index, but I can't find what EI is. It seems this is something they are expecting me to know so I can only assume it is common knowledge among academics.

What are the possible types for a journal (if a comprehensive list exists), and most importantly, for any given journal how do I find its type?
I have set up a webpage (click here) which provides links to the list of journals that are SCI, SCIE, ISI and EI and also let you check the impact factor of a journal. You can follow the links on that page to find out if a given journal is EI, SCI, SCIE, etc. Hope that it helps!
