Where can I find nav charts?

I’m trying to locate sectional charts for the US ARTCC’s, but I have no idea where to look. I am trying to track a flight on liveatc.net, and their organization is a bit sloppy, so I’m trying to figure out which sector I need to listen to. Anybody have suggestions?

Thanks.

Edit: Found this, but doesn’t show individual sector boundaries, difficult to locate the frequency for a given area if I don’t know the names.

what sector are you looking at?

Just trying to track that, don’t know which sector, that’s what I’m trying to figure out. LiveATC.net isn’t very useful in that respect.

Try http://www.skyvector.com

Thank you both. The second one is a step in the right direction, and while it is much clearer than what I found, still doesn’t have the section boundaries listed. It is still very useful, so thanks.
