Descent theory has been created by
A. Grothendieck. You can read chapters VI and VII of SGA I
(the retyped version may be found
here),
if you are interested in his early work
on the subject and if you read French.
Some pages related to descent theory: from
Bangor group ,
Alsani's categories
and descent page , Ross Street's advanced article
Combinatorial aspects of descent theory .
