This module is suitable for setups with multiple embedded views where a node needs to appear only once.
Unpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules.
Here are some key features of "Views exclude previous":
· Each view does not need to know which context it will be displayed in
· Each view can be displayed in a different context (different page, different order) without needing to change the filter
· Only the nodes that are actually displayed are taken into consideration - not those that would fall beyond the first page of the pager
· Drupal 6.x
· Drupal Views module
