I've finally finished this list which I started compiling in 2015. It's more a draft, because I'm planning to add things like publication/release dates, links to the stuff that is awailable online, collections for the short stories, and credit the authors of those descriptions that are not mine. Unfortunately, a lot of information here is taken from a thread on some forum that I can't find now, or even several of them (one was apparently a post in Silvia Moreno-Garcia's blog which may be not online now).
