Larry Niven has written over 50 books.
It's hard to work out what order in which to read them.
Maybe in the order they were written?
I think starting by reading stories set in his "Known Space" universe is a good way to go.
There are about 9 novels and 35 short stories set in this universe.
They span about 1000 years in the future and cover a small portion of the Milky way.
They begin with the first human explorations of the solar system, to humanity's expansion into other near systems.
You can probably divide this time span into 4 periods:
The Early Exploration stories cover the first human explorations and colonizations of the Solar System (Pre 2000AD).
Humanity explores The Moon (Luna), Mercury, Venus, Mars & the outer planets like Pluto.
The Slower-Than-Light stories cover later exploration and colonization of the solar system.
The time period is about 350 years (2000 to 2350AD). It's often called the Belter Period.
Belt refers to the asteroid belt of Earth's solar system, Sol system. Citizens are named Belters.
Earth is ruled by the UN (United Nations).
The Belter period features slower-than-light travel with fusion-powered and Bussard ramjet ships.
What struck me about Niven's world building was how close his vision is to that portrayed in the Sci Fi series, "The Expanse".
This time is composed mainly of Niven's Belter stories, the Gil "The Arm" Hamilton mysteries, and the novels World Of Ptaavs, A Gift From Earth and Protector.
For the record, the later "Neutron Star/Ringworld period is set around 2651 AD and later.
It features faster-than-light ships using "hyperdrive".
It is composed of many stories featuring Beowulf Shaeffer and Louis Wu, among others.
Niven later joined the last two periods into a single universe in the short story "A Relic of the Empire" (If, December 1966). Then in the 1980's he started writing stories of the Man-Kzin Wars. The first volume was published in 1988. This filled in the 300 year gap (between 2350 to 2651).
