I made another map book yesterday -- We Are The World -- with seven maps of sections of the world. Three are below. The book is 5.25 inches square, and the maps, opened out, are 10 inches square.
I really like this book structure and know it has other uses too, besides featuring maps. The oldish Rand McNally Atlas I'm using was purchased for a buck during the summer, specifically for bookmaking purposes. I'll recycle the book board covers at some point as well.
I love looking at maps. The atlas I regularly use is by National Geographic and although it is a bit dated (from the 1980s, before so many geopolitical changes in eastern Europe and the Balkans), every time I read a novel that takes place in a different part of the world, I get out my atlas and pore over it for a good hour or so.
