Thank you Praire. I'm looking for more female writers to balance out
my reading list of 50 novels... So far only got Brackett, Le Guin, Cherryh... suggestions alway welcome (female or otherwise). Looking for widest range of styles possible (pre 1985) Shsssh!, Don't tell anyone, but this thread of Pogo's is where I steal a lot of my list... lol
An important author you are missing is Robert Silverberg... maybe The Book of Skulls, Dying Inside, Downward to the Earth, or Nightwings, or a collection of short stories...
Flowers for Algernon by Daniel Keyes is a big classic. Another novel I liked is Windhaven, by George R. R. Martin and Lisa Tuttle, or from GRRM you could also try Dreamsongs, a collection of his short stories, although you could just read a selection of his most famous ones, since it's long.
Cordwainer Smith: a collection of his short fiction (The Rediscovery of Man, where again you could read a selection if it's too long), or the novel Nostrilia.
Another writer you should read is James Tiptree Jr (also works for your female author list, since she is a woman although she used a male pseudonym).. You should try a collection of her short fiction, like Her Smoke Rose Up Forever. If it's too long for you you could just choose some of the stories...
It's a pity that you have two Larry Nivens, and none of them is The Mote in God's Eye, which would have been my first choice.
It's a pity my favorite works by Octavia E. Butler are after 1985, but you might want to consider Kindred (1979)
If you want some feminist SF you might want to consider Joanna Russ' The Female Man or Suzette Haden Elgin's Native Tongue. Sherri Teper's The Gate to Women's Country is just out of your self-imposed time period (1988).
Of course, short fiction has played a very important role in the history of SF, much more than nowadays, so something like the Science Fiction Hall of Fame is a great way to follow the development of the genre.
