The libraries are not available as a separate download; you'd have to download the USA version and copy the libraries from there.
I wish it wasn't this way. While I fully understand that additional library parts are developed within different regions, and those regional offices sometimes want to restrict access to them, with increasing numbers of people working across borders, it might be time to have a global library with the best parts from all regions. Need to watch out for bloat, though.
If certain objects are developed exclusively for customers (paying extra) within that region then, by all means, put them behind a paywall, but I don't think it's good to deter the usage of standard libraries.
I think such an attempt was made (was it the ACE library?) a few years ago, but it didn't go very far. The time and resources required to maintain it must have been overwhelming. If I remember right, it also contained some objects that were proprietary, but that's a separate story.
Sorry about hijacking this thread.
