## Abstract

Computer method and apparatus manages and navigates computer implemented information. A first source information and second source information are related as parent-child information. Keywords are extracted from the first and second source information and are used to relate second source information to the first source information. This produces dynamic sets or groupings of second source information related by keywords. Display of a listing of the keywords enables user navigation of the information especially according to the groupings of second source information.
