A local map provides a picture of all of the links and nodes directly connected to the current node. The depiction may be graphical (eg. a flowchart), or textual (a simple list). In most systems, readers may select one of the nodes to make it current.
Local maps provide context for a reader, and may help in link selection. Maps are termed "browsers" in NoteCards.
Landow has noted several variations on the idea of the local map, calling them overview types.
