Trails in the Yellow Dog Mountains

Hello,
Recently I've been expanding my list of completed walks around the blue mountains area and recently completed the Katoomba to Mobbs Swamp walk. I found it to be a nice walk although the Topo Map I was using did not appear to have listed all the trails I encountered. I found myself at a point along the way which had 4 different trails each going in different directions.. I had plotted some simple compass headings and had no problems determining which directions was that of the map but I'm curious to know if there is anywhere I can find better trailed maps so I can mark them on my map for next time...
The topo map im referring to is the Dept of Lands 3rd Series (Jenolan sheet).
Cheers!
