Biblioteca Nacional (headquarters of the national library) is located in Buenos Aires at the location of the presidential palace where Eva Peron died of cancer. The library has a really huge collection of 5 million books for avid readers from any part of the world to come and enjoy. Unlike the US public libraries, you cannot go through the shelves and locate books on your own. You need to seek the help of the librarian to get any particular book. If you go to the reading rooms that are located on the top two floors, you can get an amazing view of Buenos Aires.
