Niven is best known for his Known Space series, a future history spanning the entirety of the third millennium and ranging from the galactic core to the outer rim.
Brimming with habitable worlds, richly imagined human cultures, and convincingly created alien races, Known Space is a benchmark against which other SF settings are measured.
He has also authored a number of popular novels with frequent collaborator Jerry Pournelle, including The Mote in God's Eye (and its sequel The Gripping Hand), Lucifer's Hammer, and Footfall.
With Stephen Barnes, he has written the Dream Park series, and with both Pournelle and Barnes, The Legacy of Heorot and its sequel Beowulf's Children.
Niven is also known for his essays on various topics, usually speculative nonfiction, which are engrossing and frequently hilarious.
Many can be found in the collections N-Space, Playgrounds of the Mind and Niven's Laws. In particular, N-Space and Playgrounds make a fine introduction to the breadth of Niven's work.
Perhaps most telling, however, is that the vast majority of his work has remained in print constantly since its first publication.
