If I may slightly plagarize a well-known (and doubtless copyrighted)
computer ad,

	netlib has it now!

(Sorry, couldn't resist :-) ...


Seriously, netlib has quite a bit of (excellent) Gaussian quadrature
software:
- QUADPACK is a FORTRAN subroutine package for the numerical
  computation of definite one-dimensional integrals.  It has
  a variety of subroutines in both single and double precision,
  based on various automatic and non-automatic Gaussian
  quadrature integrators.  Try "send index from quadpack"
  and/or "send readme from quadpack" for more info.
- The "golden oldies" library contains a routine for computing
  the nodes and weights for a variety of Gaussian-type quadrature
  rules.  Again, it comes in both single and double precision.
  Try "send index from go" or "send gaussq.f from go" for more
  info.
