‘图册’ (túcè) is a compound noun meaning ‘illustrated volume’—a book or booklet rich in images, often with accompanying explanatory text. The first character 图 (tú) means ‘picture’ or ‘illustration’, while the second character 册 (cè) means ‘booklet’ or ‘volume’, historically referring to ancient bamboo-strip books. Together, they emphasize a publication where visuals are central to conveying information.

This word is commonly used for reference materials such as field guides, educational albums, museum catalogs, or species documentation—especially in contexts like wildlife conservation, biology education, or art publishing. It carries a formal, scholarly tone and is rarely used for casual photo albums or digital galleries; those would more likely use terms like 相册 (xiàngcè) or 电子画册 (diànzǐ huàcè). ‘图册’ implies intentionality, organization, and informational purpose—not just a collection of pictures, but a curated visual resource.
