Library documentation

[Konrad Hinsen]

Is there any place where I can find an introductory documentation for the=
=20
Haskell libraries? To be more concrete, say I am interested in using=20
Data.Array.ST.STUArray. I would need some explanation of the ST monad, an=
d=20
then an explanation of how I can use an STUArray in an ST monad. Plus ide=
ally=20
examples. But the same applies to most of the libraries. I can't find any=
=20
documentation other than the very terse reference or the parts that happe=
n to=20
be covered by textbooks.
