A type of media that someone has requested to censor or limit access to in some way is considered "challenged"

Challenged Media

The practice of limiting or removing access to a text, film, image, news, or other information work. Censored works are often deemed offensive or dangerous.

Information behavior describes the way humans interact with information. There is an emphasis on how people seek, retrieve and utilize information.

Information Behavior

Document-centered is one of the hypertext node-link models that nodes are the holders of content, and links are the means by which the content is given context. In this model, users follow the direction of the links to navigate and focus while reading.

Document-centered hypertext

Browser-based is portrayed graphically. Authors and readers interact with the hypertext using a map. In early conceptions of browser-based hypertext, boxes or other icons symbolized nodes and lines represented the links among them; hypertext browsers were oriented toward presenting a graph representation of a network.

Spacial hypertext nodes are moving more freely. Nodes are distinguished by color, shape, and size.

Censorship 

The behavior of an information user to avoid, discard or reject information that disagrees or alters their already established point of view. This behavior can be used to reinforce bias. 

Information Avoidance

The process in which a person locates information to resolve a need.

Information Seeking

Defined as what an individual needs to know to fill in a knowledge/information gap. For example, when a patient seeks a doctor's appointment, they are looking to fill an information gap concerning their physical condition. 

Information Need

The study of how users interact with information in the library. There is an emphasis on how people seek, retrieve and utilize information.

Information Behavior in Library Science

Censorship

The concept of maintaining information past it's digital expiration. These can be as simple as updates, storage methods, and strategies for preserving websites as well as context.

Digital Preservation

Information and the utilization of it has a start, but how did it become a Science practiced by Librarians as well as Information Professionals? It started off as a concept based on epistemological use in different languages and practices that define the original word of information to mean support or educate. From that, information begins to become a science based on historical innovations that create practices for it and expands its use. In understanding Information Science at a conceptual level, it can be defined and contextualized by its origins as well as where it is going.

How can we learn from practice to design appropriate components for and
interface to a spatial hypertext system? 

How to design spacial  hypertext

For readers, the system provides an opportunity to read in context, with awareness of the related, nearby nodes. 

For writers, the system supports the development of a visual language through informal interaction with a user interface similar to a graphics editor
