Andre Norton was another prolific writer of fantasy and science fiction. I didn't really get into her books that much, but I do have a collection of her Witch World series, probably because I liked the covers of the British editions published by Tandem. They are unusual, somewhat psychedelic and bizarre. I can't recall reading many of the series, but I did like Year of the Unicorn the best.
Related books, eg Jargoon Pard is a sequel to Year of the Unicorn
Next will be old style fantasy - A Merritt, Sprague De Camp etc.
