TITLE: Why aren't proceedings from ICM 2014 on mathscinet?
QUESTION [25 upvotes]: Articles from the Proceedings of the International Congress of Mathematicians, Seoul, 2014 don't appear to be on Mathscinet. Why is this?
(Someone pointed this out to me recently, and I was reminded of it today when I tried to cite a lecture.)

To expand on Ed Dunne's reply, it may be helpful to note that each ICM organizing committee makes its own arrangements about formal publication of proceedings.   For the Seoul ICM see Seoul and for PDF files of their four volumes of proceedings see here.   Presumably in due time all of this will be incorporated into the ICM site, where one can find older proceedings:  ICM.
Nowadays most people post earlier manuscripts on the arXiv, but of course they are more troublesome to track down.   In any case, the ICM databases of speakers and sessions are useful because published proceedings are usually organized into several volumes.
