Bhutan's National Library was established in the 1967. Its mission is to preserve the literary treasures of the nation which constitute a significant element of Bhutan's rich and vibrant cultural heritage. The library was established with a small collection of precious texts, and was housed in the central tower of the Tashicho Dzhong. The collection then moved to the its present building located in the Changgandkha area of Thimphu. The building that houses the collection is a traditionally constructed four storied eight cornered building that is a homageto the central tower temple located in Bhutanese Dzhongs.
It houses an extensive collection and archive of Buddhist literary works mostly in ancient block-printed format, with some manuscripts several hundred years old. This collection, which is also known as the "Choekey Collection," mainly comprises Buddhist literature written in Choekey, the religious script of Northern Buddhism. It also includes works written both in Tibetan and in Dzongkha, Bhutan's national language. There is also a foreign literature collection which comprises works written in English with subject interest on Buddhist studies, Bhutan, the Himalayan region and neighboring countries like India, Myanmar and Sri Lanka where the Buddhist religion is also practiced.
In addition to the religious texts the repository room of the building houses old records, letter and over 7000 important photographs that form an important part of modern Bhutanese history. The archive also houses a huge microfilm collection of many other important books and documents.
