Mark Aaron Polger writes: “Libraries are complicated. They have a maze of departments, a specific method for retrieving books, and many rooms with different purposes: public and staff areas, service desks, and storage areas for materials, with varying access policies. Library signs can help guide users through this unfamiliar maze, allowing them to find what they came for with minimal anxiety. At its most basic, a library signage system should have a directory at a building’s entrance to give users an overview of the layout. Directional signage along high-use channels also aids wayfinding.”
