Early Science Fiction is going to become rather important in one of my timelines, which is unfortunate given that my knowledge begins and ends with War of the Worlds and Jules Verne. It picks up again a little in the thirties and on, but that's only barely of use.
What I need is a comprehension of proto- and early-SciFi from the late 1800s through World War Two, especially by European authors, and especially from the window 1890-1920.
Now I somewhat doubt that anyone has piles of old Science Fiction they're dying to send me, and I will be mostly digging around on my own, but I'd appreciate recommendations of books, authors, or websites to investigate.
