Many years ago my first Precept Bible study leader shared her key word marking system with our class -- she color-coded by theme & I've tried to incorporate her system as much as possible (not always successfully but it helps me be consistent when marking than I would be otherwise). This JPEG book mark can be printed on photo paper (8.5 X 11" in landscape) for a handy reference. I just cut them apart so that they make three bookmarks. The other option is to laminate them, which I used to do, but that makes for a really stiff bookmark. The photo paper is thicker and stronger than printer paper but not too stiff.
I'm not sure where to put this blog or how to classify it. This blogger is a daughter of a friend and while I'm pretty sure she's a Christian, it isn't a Christian blog, or books & reading or letter writing & mail art. It's basically about their travels so I'm putting it here for now: Jen's blog: 3toGo
