A post by Grace Neveu and Jake Johnson at Archive.org reports on a project to digitize all of Balinese literature (as this brief notice says, “They are in the running for being the first culture to have their entire literature go online, even current writings and lectures”):
The documents are centuries-old lontar palm leaves incised on both sides with a sharp knife and then blackened with soot…. The writings consist of ordinary texts to sacred documents on religion, holy formulas, rituals, family genealogies, law codes, treaties on medicine (usadha), arts and architecture, calendars, prose, poems and even magic. The estimated 50,000 lontars are kept by members of the Puri (palace) family and high priests to ordinary families. Some are carefully kept as family heritages while others are left in dirty and dusty corners of houses. Digitizing the lontars makes them available to scholars and students and salvages the documents from getting destroyed by insects or humidity, as many already have.
At the link you can see images of lontars, watch a video of a performance, and follow further links. Thanks, Yoram!
