The Gandhāran Buddhist texts are the oldest Buddhist manuscripts yet discovered, dating from about the 1st century CE. They are written in Gāndhārī, and are possibly the oldest extant Indian texts altogether. They were sold to European and Japanese institutions and individuals, and are currently being recovered and studied by several universities. The Gandhāran texts are in a considerably deteriorated form (their survival alone is extraordinary), but educated guesses about reconstruction have been possible in several cases using both modern preservation techniques and more traditional textual scholarship, comparing previously known Pāli and Buddhist Hybrid Sanskrit versions of texts. Other Gandhāran Buddhist texts—"several and perhaps many"—have been found over the last two centuries but lost or destroyed.
The texts are attributed to the Dharmaguptaka sect by Richard Salomon, the leading scholar in the field, and the British Library scrolls "represent a random but reasonably representative fraction of what was probably a much larger set of texts preserved in the library of a monastery of the Dharmaguptaka sect in Nagarāhāra."
In 1994, the British Library acquired a group of some eighty Gandharan manuscript fragments from the first half of the 1st century. These birch bark manuscripts were stored in clay jars, which preserved them. They are thought to have been found in western Pakistan, the location of Gandhara, buried in ancient monasteries. A team has been at work, trying to decipher the manuscripts: three volumes have appeared to date (2009). The manuscripts were written in the Gāndhārī language using the Kharoṣṭhī script and are therefore sometimes also called the Kharoṣṭhī Manuscripts.
The collection is composed of a diversity of texts: a Dhammapada, discourses of the Buddha such as the Rhinoceros Sutra, avadanas and Purvayogas, commentaries and abhidharma texts.
