TITLE: What's wrong with Advanced Studies in Contemporary Mathematics (Kyungshang)?
QUESTION [10 upvotes]: By some reason the Journal mentioned in the title is no longer covered by the AMS Math. Reviews. On the MathSciNet web page it says:
Last Issue: 24, no. 1  2014
Indexed cover-to-cover 
Status: No longer indexed
The journal, however, still exists and it is still covered by the Zentralblatt. I have written to the journal and the AMS several times already and asked for the reason why the AMS doesn't review this journal any more and I have got no answer from either side!
Does someone know why this journal is no longer indexed?

REPLY [17 votes]: There has been an explosion in new allegedly "scholarly" journals because they are profitable and many university libraries have lost control over their inventory due to the "big deal" they were trapped into a decade ago where they were lured by lower prices into relinguishing autonomy over subscription decisions, currently made in a centralized fashion. The result is a rapid decline in quality and a rapid increase in quantity. MathSciNet had to deal with this by terminating their coverage of numerous journals and not merely this particular item from Kyungshang. Just because the title the folks in Kyungshang chose is very similar to an AMS publication (Contemporary Mathematics), which is a common practice among the new crop of so-called scholarly journals, is not a reason to suspect foul play on the part of the AMS.
