The first visual impression being library spaces are stagnant & boring. The existing index do not communicate efficiently to the user about the book location. As the communication is not effective, the user comes back to librarian repeatedly to find out the required book. In library the core problem is about the Geometry. Practically there is a light cone which forms when light is fallen from a certain height and does not reach to the required area and also create a shadow . so that’s why user can not read easily the title of books. Also the gap between the racks is very less for an user to bend down & search books in the lower shelves and also for a circulation.
