Established in 1976 in order to preserve ancient texts both in Dzongkha and Tibetan, the National Library is a good resource for books about Bhutan.

Scriptures from all religious schools are represented here, including that from Bon tradition. Most of the books are printed on long strips of handmade paper stacked between pieces of wood and wrapped in silken cloth. Also on display are ancient photographs, a copy of the 1783 letter sent by the Desi (Secular Ruler) to Samuel Turner – a British army officer and surveyor.
