To be added
Here are some things that should be added to this page: RobHar (talk) 01:23, 27 December 2008 (UTC)
 * Satellite functors
 * (co)Effaceability and universality of delta-functors
 * dimension shifting
 * examples (application of universality, satellite functors that aren't derived functors, delta-functors that aren't universal, use of dimension shifting)
