Abstract

A system, apparatus, and article of manufacture for detecting a reader'"'"'s interest in a particular external document through their markings and annotations, and processing the marks in various ways, is provided. By detecting anchors proximal to annotations made by a reader, a collection of the annotated anchors and the related documents may be organized and generated for a reader to process according to their desires.
