Abstract: Techniques are provided for understanding interconnected documents. A citation is identified in a first document that points to multiple portions of a second document. Hovering over a link proximate to the citation displays a multi-popup containing links to one or more of the portions of the second document. Hovering over one of the multi-popup links displays a second popup containing an associated portion of the second document. Instances of the citation, in whole or in part, are highlighted in the second popup. Within the second popup, additional citations are identified and links to associated content are generated, such that hovering over a citation contained in the second popup displays a third popup.
