Well, the standard prelude is the first thing to read:
http://www.haskell.org/onlinereport/standard-prelude.html

Then refer to the standard libraries:
http://www.haskell.org/ghc/docs/latest/html/libraries/index.html
for lots more.

Also in Part II of the report, there's further documentation for some
of the libraries (though they have been moved into the hierarchy).
