In my university listing of certain journal in SCI is thumb rule for good reputation of journal. Beside this, there are other journals which have indexing in Zentralblatt MATH, AMS Digital Mathematics, Google Scholar, CiteFactor etc.
Can I consider them good too? What if a journal do not assign DOI numbers to its articles ? Can we still count that journal as reputed ?
So, please explain in detail real meaning of reputation of journals other than listed in SCI.
