?RNG comes with copious references, and the sources are in src/main/RNG.c.

Well, there is a very extensive literature, and you don't give your
background. I would suggest starting with either my 1987 book `Stochastic
Simulation' or Knuth's TAOCP. The principles were worked out long ago,
and the world is in no need of yet another PRNG. (There are far too many
that have been heavily promoted and a few years later discredited.)
