I did not find any direct way to check if a journal or conference is included in IE (please let me know how), but one whose university has access to IE can look for a specific paper published in CICLing and see whether they are included; if this one is included then the whole conference is included.
Here are the search results for a random paper from CICLing 2007, and here for a random paper from CICLing 2008. In both cases the paper was found in the IE; therefore both conferences were indexed. We expect that IE will continue their coverage of CICLing.
