Latvia is requesting that two more items of its unique cultural heritage are recognized for inclusion in a UNESCO "Memory of the World" list, reports.

The list is updated every four years, and this time it is planned to add a collection of letters written in Siberia on birch bark, plus the drawings of Johann Christoph Brotze, who recorded the dress and customs of the local populations during the 18th and 19th centuries and a collection of wax cylinders from the early 20th century which provide a unique record of Latvian folk songs.

Also deemed worth of inclusion are hand-written prayers and sermons by members of the Moravian brotherhood or Herrnhuters, a protestant sect who were forced to copy their books by hand as a result of repression under Tsarist rule in the 18th century, explained Sarmīte Pulste, representative of the Latvian National Committee of UNESCO.

Currently, the International Register has two objects from Latvia - The "Dainu skapis" collection of Daina poems compiled by folklorist Krišjanis Barons in the 19th century and documents relating to the Baltic Way events of 1989.
