Abstract: 
We present first results of a comparison of emission line shift properties for the high (HILs) and low (LILs) ionization lines in 43 low-redshift quasars. We identify a core sample of C IV lambda 1549 and H beta profiles with a wide distribution of red- and blueshifts (less than or equal to+/-1000 km s(-1)). We also identify two tails in this distribution: one with large HE redshifts (greater than or equal to 2000 km s(-1)) and another with large C IV blueshifts (greater than or equal to 1500 km s(-1)). The tails are mutually exclusive. All objects with extreme H beta redshift are radio loud, and all objects with extreme C IV blueshift are radio quiet. The core samples of smaller shifts can be most simply divided into: (1) H beta-a red-shifted radio-loud population (related to the tail) acid a radio-quiet population with mean shift near zero, and (2) C IV-a blueshifted radio-quiet population (related to the tail) and a radio-loud population with mean shift near zero. The results suggest fundamentally different kinematics for the HILs and LILs. They also suggest very different kinematics for radio-loud and radio-quiet active galactic nuclei. They also favor a predominance of radial motion in a large fraction of the sample.
