Most integration formulae that were known in 1971 are listed in the book
A.H. Stroud: Approximate calculation of multiple integrals,
Prentice Hall, Englewood Cliffs, N.J., 1971
Since then a lot of new integration formulae were constructed. The report
R. Cools and P. Rabinowitz:
Monomial cubature rules since 'Stroud': a compilation,
Report TW161, Dept. of Computer Science, K.U. Leuven, 1991.
contains now 99 references.
