I have always imagined Paradise as a kind of library.
Jorge Luis Borges, in Dreamtigers (1960)
The postcard shows The Long Room of Trinity College in Dublin, Ireland. It's the main chamber of the Old Library, 65 metres long and there are about 200,000 of the oldest books of the collection. It was one of the most amazing rooms I've ever been in. I visited it in July 2012.
