Good stuff.
Essential Ellison is a great book, I've checked it out from the library but would love to own it.
I want that one and Maps in the Mirror, the collection of Orson Scott Card short stories.
I'm reading Motherless Brooklyn as well, I'm about 2/3 of the way done. I think I liked Men and Cartoons better, but I also think I'm more of a short story fan. (For instance I enjoyed the PG Wodehouse short stories I've read more than the novels).
I'm still slowly working through the Complete Lovecraft, and I also just got a book of CJ Cherryh's short stories. Between big books, long games, and complete series DVD sets, I rarely actually finish anything.
I have read Door into Summer, and while I'm sure I enjoyed it, I don't remember too much about it, so it must not have made too much of an impression.
