Great, thanks for the link!

Choosing a library is something one should consider only after he has gained some insight of the language.

Well, like I said, I've tinkered with OCaml in the past and have a reasonable idea what it has to offer. While I still have a lot to learn before I can properly make use of OCaml idioms and such, I would prefer if I didn't have to relearn the library as soon as I get to a level where I can write real programs. From the link I see that Batteries is backwards compatible with the standard library, so perhaps its the better one to start with for a beginner.
