I've started a catalog numbering system

I'm starting to get a little more organized in my old age... I've got some catalog numbering going on on my main blog, http://www.jeffthomannsart.blogspot.com. I may or may not put the catalog numbers in here for doodles. I'm not exactly sure yet. Just trying to figure things out and sort out my stuff and get it online in as neat a way as possible... doing that whole creation from chaos thing is great, but time consuming, and a bit draining to my mental capacity at times.
