Abstract:

The hypertext world has classically distinguished between two fundamentally different ways of presenting hypertext nodes on the screen: scrolling and cards. Throughout the history of hypertext, designers of hypertext systems have argued about the relative merits of these two contrasting approaches. The proponents of the scrolling model are sometimes called the holy scrollers and the proponents of the card model are called the card sharks. Here are examples of documents I have authored myself in these two models, using pre-WWW hypertext systems.
