Sharp textures?

I want to write fine text on the walls in a room (I’m making this study maze), so that one could add many pages (e.g., one chapter) of a book onto the walls of one room, so that one cold read these pages by approaching the wall. Is there a way to add sharper textures onto walls (i.e., so that walls would work like Google Maps - increasing resolution as you approach them)?

Easiest way is to just use a high resolution texture and enable mip-mapping on it. The other way would be to use an LOD node to swap out the model that the text is applied to for a different model with a higher resolution texture as you get closer to it.
