[CATEGORIES] is a work of hypertext, in a form the author calls a tagnovel. Hyperfiction is generally built around hyperlink usage, but still there are no narratives built on the concept of tags. The tagnovel concept is an attempt to deal with the idea of the world divided in categories, as well as people, relations, social interaction, personal actions and decisions and identity. The narrative explores these concepts of categorization, territories and social practices that are ultimately analogic to our activity on the computer.
