E12 Shape Based Chinese Character Index is a reference resource for exploring Chinese characters through their visual structure. It organizes entries by shape-based categories, beginning with the “口” component and grouping characters under a series of initial shapes, including 冂, 凵, 厂, 丿, 丶, 人, 一, 丨, and 十. The index lists characters such as 員, 呈, 品, 單, 哭, and 咢, alongside related forms and character groupings.

It also presents additional index sections for other components and categories, including 足, 民, 尸, 日, 目, 貝, and 見. Navigation labels refer to initial and final shapes, phone shapes, phone initials and finals, English, and categories, indicating a broader framework for organizing and consulting character information. This resource is aimed at people who want to examine Chinese characters by their written forms rather than relying only on pronunciation or meaning.
