National Book Trust, (NBT) is an Indian publishing house, founded in 1957 as an autonomous body under the Ministry of Education within the Government of India.

Jawaharlal Nehru envisioned that the NBT would be a bureaucracy-free structure that would publish low-cost books. They publish a monthly Newsletter about recent publications.

The activities of the Trust include publishing, promotion of books and reading, promotion of Indian books abroad, assistance to authors and publishers, and promotion of children’s literature. NBT publishes reading material in several Indian languages for all age-groups, including books for children and neo-literates. NBT's children's books are known for their illustrations, by illustrators such as Pulak Biswas, Jagdish Joshi, Mrinal Mitra, Subir Roy, Atanu Roy, Manjula Padmanabhan, Mickey Patel and Suddhasattwa Basu. Painters Jatin Das and Krishen Khanna have also illustrated books for the Trust.

Shah Hussain (1538–1599) was a Punjabi Sufi poet who is regarded as a Sufi saint. He was the son of Sheikh Usman, a weaver, and belonged to the Dhudha clan of Rajputs. He was born in Lahore (present-day Pakistan). He is considered a pioneer of the Kafi form of Punjabi poetry.

Shah Hussain's love for a Brahmin boy called "Madho" or "Madho Lal" is famous, and they are often referred to as a single person with the composite name of "Madho Lal Hussain". Madho's tomb lies next to Hussain's in the shrine.

His tomb and shrine lies in Baghbanpura, adjacent to the Shalimar Gardens. His Urs (annual death anniversary) is celebrated at his shrine every year during the "Mela Chiraghan" ("Festival of Lights").

Hussain's poetry consists entirely of short poems known as Kafis. A typical Hussain Kafi contains a refrain and some rhymed lines. The number of rhymed lines is usually between four and ten. Only occasionally is a longer form adopted. Hussain's Kafis are also composed for, and have been set to, music deriving from Punjabi folk music. Many of his Kafis are part of the traditional Qawwali repertoire. His poems have been performed as songs by Nusrat Fateh Ali Khan, Abida Parveen and Noor Jehan, among others.
