Ok, this one has been bugging me for a while now. Back in, I would say the mid-80's, I owned a hardcover book with a white dust jacket featuring a full-color photo of Saturn. I thought it was called 'The Planets' or 'The Solar System', but I haven't been able to find it under those titles. The book had one section for each planet, consisting of a nonfiction essay and a science fiction short story based on that planet. I remember in particular that Bradbury's "All Summer in a Day" was the featured story in the Venus section, but the book doesn't seem to be in the IFSDB list for that story. Thanks!
