NoteCards is a hypermedia system for designers, authors, and researchers to analyze information, construct models, formulate arguments, and process ideas [Halasz, 1988]. Its basic framework is a semantic network composed of notecards connected by typed links. It provides users with tools for displaying, modifying, manipulating, and navigating through the network.
NoteCards contains four basic constructs: notecards, links, browsers, and fileboxes. Notecards contain information embedded in text, graphics, images, voice or other media. Links represent binary relationships between cards. Browsers display node-link diagrams of portions of the network. Fileboxes provide a mechanism to organize cards into topics or categories. NoteCards can be integrated with other systems running in the Lisp environment such as mail systems, databases, and expert systems.
