Is there any website for announcements of journal's special issues? I was wondering if there is a site or something where I can find announcements for all (most of) the special issues of journals (upcoming and past) . For example of Springer, IEEE, Elsevier, ... 

If I search for this now, I find scattered call for papers. Also, I can't seem to find this on wikicfp.
No, there is not.

Speaking as somebody who has dealt with a number of special issues on both sides of the editorial table, there is simply too little coherence in how different journals advertise their special issues.  Sometimes it's hard even to find a coherent explanation of how a journal is approaching special issues even on its own website.

Maybe somebody like Google could address this, but it would be a hard problem requiring either serious investment in human curation or serious natural language processing mojo.
