  This paper is a study of three-dimensional paracontact metric
(\k{appa},{\mu},{\nu})-manifolds. Three dimensional paracontact metric
manifolds whose Reeb vector field {\xi} is harmonic are characterized. We focus
on some curvature properties by considering the class of paracontact metric
(\k{appa},{\mu},{\nu})-manifolds under a condition which is given at Definition
3.1. We study properties of such manifolds according to the cases \k{appa}>-1,
\k{appa}=-1, \k{appa}<-1 and construct new examples of such manifolds for each
case.
