All,

In this Survey of blog and wiki posts on Relation Theory, relations are
viewed from the perspective of combinatorics, in other words, as a topic
in discrete mathematics, with special attention to finite structures and
concrete set-theoretic constructions, many of which arise quite naturally
in applications.  This approach to relation theory is distinct from, though
closely related to, its study from the perspectives of abstract algebra on
the one hand and formal logic on the other.
