"31 Best Soft Science Fiction Books" from best-sci-fi-books.com.
From the article: "Soft science fiction tends to focus more on people and relationships than on technical details; more on humanity than technology (even though there's usually some cool technology).
Science fiction author Poul Anderson, in Ideas for SF Writers, described H. G. Wells as the model for soft science fiction: "He concentrated on the characters, their emotions and interactions" rather than any of the science or technology behind, for example, invisible men or time machines."
