For example (not a wonderful example, as I know the answer :-)) if I'm writing a program and I need to build a parser, what's to tell me (apart from asking around, or stumbling on it) that Parsec is the library I want - or if I know that, that it's included in the standard library and I don't need to go and install it?
Thus you need a list of availible libraries to get to know wether they will fit your needs... The only "index" I know of is www.haskell.org -> link Applications and libraries ... Another way would be goto darcs.haskell.org and browse the folders. Many libs are located there (of course not all) Another "list of libraries" can be found in gentoo portage overlay http://haskell.org/~gentoo/gentoo-haskell Some standard packages can be found in one source file eg Some additional libraries can be found here http://www.haskell.org/ghc/dist/current/dist/ -> *extra-libs* If this and google didn't help you I would ask ;) Marc Weber
