As of 2013^[update], the library in Bangkok housed over three million items and had 11 provincial branches. Its budget was 87 million baht and it employed about 200 staff.^[3]

The National Library of Thailand's main tasks are collecting, storing, preserving, and organizing all national intellectual property regardless of medium. Collections include Thai manuscripts,^[4] stone inscriptions, palm leaves, Thai traditional books, and printed publications as well as audio-visual materials and digital resources. The library is a national information resource serving citizens nationwide.

The National Library has a long history. Its precursor was the Phra Vajirayana Royal Library (Thai: หอสมุดพระวชิรญาณ) which was established in 1883, by sons and daughters of King Mongkut (Rama IV) to honor their royal father. Later in 1897, King Chulalongkorn returned from his European visit and expressed his desire to dedicate the Vajirayana Library to the Capital. In 1905, three libraries, the Mandira Dharma Library, the Vajirañāṇa Library, and the Buddhasasana Sangaha Library, were amalgamated at the command of King Chulalongkorn and renamed the "Vajirañāṇa Library for the Capital City". The library has remained under royal patronage since that date. In 1933, after democratic reforms, the Fine Arts Department was established and assumed administration of the Vajirañāṇa Library by royal decree. It was subsequently renamed the "National Library". In 1966, the National Library was relocated to Samsen Road in Bangkok and is now administered by the Ministry of Culture.
