Three-Dimensional Artefacts and Realia可譯為「立體藝術品及實體」或「立體資料」。立體資料的概念較符合AACR2 10.0A1所定義的適用範圍。AACR2 10.0A1：The rules in this chapter cover the description of objects of all kinds added to library collections (other than those covered in the other chapters of Part 1). Those include models, dioramas, games, puzzles, sculptures and other three dimensional art works, exhibits, clothing, and naturally occurring objects (including microscope and other specimens). Optionally, use these rules to describe the devices/equipment used to read, hear, view, etc., resources.可知立體資料包含：模型、立體畫(dioramas)、立體佈景、玩具、拼圖、雕塑及其他立體藝術品、展品、機器、衣物用品、和自然生成的物件(顯微鏡標本及其他樣本)等。但不包括立體測繪資料(立體地圖、球儀等)。錢月蓮敬答 20141224
