Time for a redo on the bookshelves

This may be like airing dirty laundry.. but I am getting ready to redo my bookshelves. Some of this did not originally go on the shelves... they're just there ready to be placed somewhere. I have some milk glass that I am considering putting in there. Also, I have two shelves to install that years back I had removed. The colors in the room are a light olive green and brown. The old National Geographics date back to the 1930's and I love them, but it's time to put them somewhere else. I would like to see a nice mixture of books, plates or vases... something of that nature. Suggestions?? And the deer head stays. I know. That's another subject.
