Design a library that blends historical elegance with modern functionality, inspired by the architectural style of Louis Isadore Kahn. The library's exterior should feature a monumental, timeless presence, with clean lines and geometric forms. Utilize natural materials such as stone and brick to convey a sense of permanence and history. Large, rectilinear windows should be strategically placed to allow ample natural light to flood the interior, creating a serene and contemplative atmosphere. Incorporate Kahn's signature use of light and shadow to enhance the architectural experience. The library's entrance should be grand and inviting, with a tall, recessed doorway framed by massive stone columns. Inside, design expansive reading halls with high ceilings and exposed structural elements, showcasing the beauty of raw materials. Integrate quiet study nooks and intimate reading spaces, emphasizing the relationship between the built environment and human scale. The library should also feature an atrium with a skylight, allowing natural light to filter down into the heart of the building, reminiscent of Kahn's iconic use of central light sources. Include modern amenities and technology seamlessly integrated into the design, ensuring the library serves both its historical and contemporary purposes.
