Ian Baldwin reviews "The Grid Book":
"Higgins defines the grid as "an organized set of modules that allow for manipulation and creativity." Her first chapters, which postulate brick walls and tablet writing as proto-grids that have been with us for thousands of years, suggest that this modularity has an instinctual appeal to humans. City plans and map projections formalized the grid as a field of intersecting lines, which gave us the Mercator projection. This gridded worldview is everywhere-and The Grid Book is at its most intriguing uncovering some of the less obvious manifestations."
