Existing copies of Kakawin Sutasoma have survived in the form of handwritten manuscripts, written both on lontar and on paper. Nearly all surviving copies originated in Bali. However, there is one Javanese fragment surviving which forms part of the 'Merapi and Merbabu Collection'. This is a collection of ancient manuscripts originating from the region of the mountains of Merapi and Merbabu in Central Java. The survival of this fragment confirms that the text of Kakawin Sutasoma is indeed Javanese rather than Balinese in origin.
