Perspectives on annotationsPerspectives on annotations

“Annotations are short, often rudimentary symbolic or written statements or small drawings, that are related to a specific location within a document and are also integrated firmly into the meta context of the document.”

(Schilit, Golovchinsky, & Price, 1998)

“The operation to annotate is integrated into the process of reading, it is a component of active reading.”

(Schilit, Golovchinsky, & Price, 1998)
