Abstract
This article is a survey of existing hypertext systems, their applications, and their design. It is both an introduction to the world of hypertext and, at a deeper cut, a survey of some of the most important design issues that go into fashioning a hypertext environment. The concept of hypertext is quite simple: Windows on the screen are associated with objects in a database, and links are provided between these objects, both graphically (as labelled tokens) and in the database (as pointers). But this simple idea is creating much excitement. Several universities have created laboratories for research on hypertext, many articles have been written about the concept just within the last year, and the Smithsonian Institute has created a demonstration laboratory to develop and display hypertext technologies.

Structured answers for a large structured document collection

TL;DR: This paper shows how the formation of the hypertext, the retrieval of nodes in response to content based queries, and the presentation of the nodes can be achieved in a way that exploits the knowledge encoded as the structure of the documents.
