The Department of Sri Guru Granth Sahib Studies is one of the principal research department which is concerned with the ethos of Punjab. Sri Guru Granth Sahib is the basic scripture of Sikhism. Sikhism is a revealed religion and very young in the history of world religions. It was founded in the land of Punjab by Guru Nanak (1469 to 1539 A.D.) and the last in line was Guru Gobind Singh (1666 to 1708 A.D.). The tenth and the last physical Guru created the Khalsa on Baisakhi of 1699 A.D. which brought forward the new dimension in the line of Shabad Guru. Guru Granth Sahib was compiled by the fifth Guru, Guru Arjan Dev ji, in 1604 A.D. The hymns of his four predecessors and the popular hymns of the Hindu Bhagats and Muslim Sufis as well was handed over to him at the same time of his installation as Guru. Bhai Gurdas was the scribe to the first copy under the supervision of Guru Arjan Dev. The tenth and the last Guru, Guru Gobind Singh ji Added the Bani of Guru Tegh Bahadur to the volume (known as Damdani Beer). The Guruship was bestowed by the tenth Guru in the formal manner before his departure from this world. After that the Granth became the  Guru of the Sikhs. This is the only scripture in the world which was compiled by one of the Gurus. The most unique feature of Sri Guru Granth Sahib is in being the Shabad Guru, the only Scripture which had been bestowed with the title of the Guru, the Guide in a formal manner for all times to come. Another distinctive feature of the Granth is that it is arranged in the musical measure in which a hymn is meant to be sung. This is the only Scripture in the world which has brought together the views of such Saints and Bhagats who belong to the faiths other than its founders' faith.

The Department of Sri Guru Granth Sahib Studies was established to do research on Sikhism and the Sikh Scripture. Its main function and aim is to study Sikh Religion as an academic discipline and the Scriptures from different perspectives to produce the source material for the scholars as well as the students working in the field of Sikh Studies. This is the only research department of its kind in the area of religious studies.  There are chairs in the different Universities related with Sikhism. A full-fledged research department regarding Sikh Scripture was only established in Punjabi University, Patiala. The department has very wider scope as there is not a single aspect of human life which is not dealt with in the Sikh Scripture such as Metaphysics, Spirituality, Sociology, Psychology, Ethics, Philosophy, Aesthetics, Political system and so on. No systematic academic studies have been done in the past on the collective level. The department has produced a lot of source material through the research and seminars.

The department has also set up a school of theology, the first school of its kind in the country. It has also introduced two courses, including a Certificate Course in Sri Guru Granth Sahib and a Post Graduate Diploma in Sikh Ideology. Another course in Hermeneutics, the theory and methodology of interpretation, especially of scriptural text, is in the pipeline. All the newly introduced courses are based on the international system of studies.
