Interesting! These look like the same system that Levenger calls Circa. I agree, it’s a great system for class notes. I carry just one main notebook to classes, and then separate out the pages into individual notebooks each week.
Just so you know, you can purchase these through their website: http://www.adocsystems.com. I hope you don’t mind me posting this here, I just thought it would be convenient if you wanted to purchase them.
It been some time since any of these posts, but I just came across this and tried the link to adoc systems, and it doesn’t work. I’ve seen Levenger’s version of this type of product (Circa). Has anyone seen anything else like this in the US?
