I suggest having an acrylic box made to about 1" larger height, width, and depth than the book, with the bottom left open. Showcase Acrylics in Chicago can built it out of Museum Optium Acrylic, which is optically coated, anti-reflection, and UV-filtering. All light is damaging, but this acrylic would be the most protective and visually best for the purpose.
Then make a frame-base for the box to rest in. The box's open side should fit neatly in the frame's sight dimension, so it may be lifted off at will; no tools required. When the box is in place, the assembly would be dust tight and protected from mechanical damage.
Put Bump-Ons in all 4 corners to prevent marring the table top, and use an attractive, durable fabric-wrapped board in the frame to support the book.
