Clifford D Simak (1904 - 1988) was honored by fans with three Hugo awards and by colleagues with one Nebula award and was named the third Grand Master by the Science Fiction and Fantasy Writers of America (SFWA) in 1977. He started writing for science fiction pulp magazines in 1931, but dropped out of the field by 1933. The only science-fiction piece that he published between 1933 and 1937 was The Creator (Marvel Tales #4, March–April 1935), a notable story with religious implications, which was at the time a rarity in the genre of science fiction. Once John W. Campbell began redefining the field in late 1937, Simak returned to science fiction and was a regular contributor to Astounding Stories throughout the Golden Age of Science Fiction (1938–1950). His first publications, such as Cosmic Engineers (1939), were in the traditions of the earlier superscience subgenre perfected by E. E. "Doc" Smith, but he soon developed his own style, which is usually described as gentle and pastoral. During this period, Simak also published a number of war and western stories in pulp magazines. His best known novel may be City, a collection of short stories with a common theme of mankind's eventual exodus from Earth. Simak continued to produce award-nominated novels throughout the 1950s and 1960s. Aided by a friend, he continued writing and publishing science fiction and, later, fantasy, into his 80s. He believed that science fiction not rooted in scientific fact was responsible for the failure of the genre to be taken seriously, and stated his aim was to make the genre a part of what he called "realistic fiction."
1. Empire - In a future time, the solar system is powered by one energy source, controlled by one huge organization, which has plans to use this control to dominate the planets. Unknown to them, a couple of maverick scientists accidentally develop a completely new form of energy supply and threaten the corporation's monopoly. Naturally, the corporation can't allow this to happen... A stunning story about the manipulation of pure energy, climaxing in interstellar conflict.
2. The World That Couldn’t Be -Layard was a curiosity to sociologists. The planet supported thriving tribes of natives but they were genderless. How could tribes form without families? But Gavin Duncan didn’t care. He had come to Layard to farm Vua plants. Their berries cured mental illnesses and were one of the most expensive commodities in the galaxy. He was going to make his fortune if he could just keep the Cytha at bay, a big, dumb animal that could munch through 10 rows of vua in a night. Despite native superstitions he was going to have to hunt and kill the pest if he was to protect his crop. It was a dim-witted beast. How hard could it be? – 'The World That Couldn’t Be' was first published in the January 1958 issue of Galaxy Science Fiction magazine.

9. Project Mastodon - Clifford Simak deals with the implications of time travel in his own unique way in this story. What if a group of guys did it on their own, without any help from government or industry? On a shoestring, so to speak? Would anyone believe them? What would you do if you could go back 150,000 years to a time when mastodons and saber toothed tigers roamed North America? And what happens when they run out of money? All these questions are explored in the usual humorous, wry Simak way in this story.
10. Hellhounds of the Cosmos - From Astounding Stories of 1932. Earth is being attacked by horrible black monsters that appear from nowhere and destroy and kill everything and everyone in their paths. Nothing affects them, nothing stops them; they are impervious to all weapons. Earth is doomed. But there is one hope and it rests on the shoulders of 98 brave men. Can they do it? can they find a way of retaliating?
