[Haskell-cafe] documentation of Haskell's hierarchical libraries

[s nedunuri]

I am wondering where I might be able to get a reasonably complete 
documentation of Haskell's libraries. I was using the documentation at 
https://downloads.haskell.org/~ghc/latest/docs/html/libraries/ but I 
noticed that it was missing hash tables, which are located in 
Data.HashTable. I am not sure what other modules might be missing from 
there. Is there some place where everything (up to some release) is 
documented?

thanks

PS the documentation bundled with the Haskell Platform (7.10.2-a) is 
even worse as its missing large sections of what you find at the online 
documentation
