Is the proceedings of WG 2015 published?
I am an author of a paper that is to appear in the WG 2015 proceedings. As far as I know, they have not appeared yet, which is indeed quite strange.

Early February I emailed the chair (Ernst Mayr) to ask for the page numbers of my paper; they were not yet known at that time. The chair informed me that he encountered a big technical problem when producing the files for the proceedings, but that the problems were cleared up and that he was in almost done compiling. If you want up to date info, I suggest emailing Ernst Mayr.

PS: The LNCS volume number will be LNCS 9224.
