When especially necessary, the Commissioner of the Agency for Cultural Affairs selects folk-cultural properties among those other than important intangible folk-cultural properties as 'intangible folk-cultural properties for which records should be prepared' (commonly-called selected intangible folk-cultural properties), and supports researches and recording conducted by local public bodies.
重要無形民俗文化財以外の無形の民俗文化財のうち特に必要のあるものを文化庁長官が「記録作成等の措置を講ずべき無形の民俗文化財」（通称選択無形民俗文化財）として選択し、地方公共団体の行う調査事業や記録作成の事業に助成を行っている。
