Young brown dwa rfs are particularly exciting as objects with masses in the range of e xtrasolar planets are within in reach of direct observations in the ne ar and mid-infrared. These objects can provide a laboratory for detail ed quantitative study in a context where light from a parent star does not mask the source properties of the planetary-mass object. In the p ast decade\, young brown dwarfs have been found with increasing freque ncy\, though planetary-mass brown dwarfs have remained largely elusive . Only a handful of potential planetary-mass brown dwarfs are known\, but the intrinsic faintness of these objects and the uncertainty in ev olutionary models makes determining their masses and ages very difficu lt. In this talk\, I will describe two new and efficient methods for f inding planetary-mass brown dwarfs. I will also discuss ways in which we can test evolutionary models of brown dwarfs using large spectrosco pic databases and high resolution imaging.
