The value of publishing information on the Internet is in the combination of access and connections. Most major cultural institutions and businesses today have created an Enterprise Web Space: many web sites, databases, publication collections, and related digital resources. To assure that these collections serve the intended audience, we must apply information architecture principles to organize the information in relation to users' needs. The role of Information Architecture is a combination of information analysis and visual design, identifying and visualizing structures that help users find and follow connections. We will focus on examples of Enterprise Web Space from selected cultural institutions and businesses including museums, libraries, and international companies.
