We present optical longslit observations of the complete sample of 71 Type 2active galactic nuclei (AGNs) with double-peaked narrow emission lines at $z <0.1$ in the Sloan Digital Sky Survey. Double-peaked emission lines are producedby a variety of mechanisms including disk rotation, kpc-scale dual AGNs, andNLR kinematics (outflows or inflows). We develop a novel kinematicclassification technique to determine the nature of these objects usinglongslit spectroscopy alone. We determine that 86% of the double-peakedprofiles are produced by moderate luminosity AGN outflows, 6% are produced byrotation, and 8% are ambiguous. While we are unable to directly identify dualAGNs with longslit data alone, we explore their potential kinematicclassifications with this method. We also find a positive correlation betweenthe narrow-line region (NLR) size and luminosity of the AGN NLRs(R$_{\mathrm{NLR}}\propto \; {\mathrm{L}_{\mathrm{[OIII]}}}^{0.21 \pm 0.05}$),indicating a clumpy two-zone ionization model for the NLR.
