Flicking through page-based documents with thumbnail sliders and electronic dog-ears

Current interfaces for electronic page-based documents, such as books or magazines, offer support for navigation based on explicit reference (hyperlinks) or page-numbers. These methods don't resemble the view of page-content a reader has when browsing paper documents. In this paper we describe a method for navigation based on the coarse mental image readers have of a page they have seen before. We discuss experience from using two implementations and ongoing work on a Designer's Sketchbook, where the method is further developed.
