We found 171 white dwarf (WD) spectra with metal lines (mainly just CaII lines, but some with Mg lines) in the Sloan Digital Sky Survey (SDSS) Data Release Four (DR4) White Dwarf Catalog (Eisenstein et al. 2006). WDs with metal lines are providing a lot of excitement these days with the discoveries of debris disks around DAZs (Becklin et al. 2005; Kilic et al. 2005; Kilic et al. 2006) and the first detailed analysis of a DAZB (Koester et al. 2005). In light of such interesting works, we looked through the DZs identified in the SDSS DR4 WD catalog to find new candidates for further studies. We found 20 DZs with H lines (DAZs and DZAs, 12 DZs with He lines (DBZs and DZBs) and 11 DZs showing both H and He lines (six DBAZs, two DZBAs and five DBZAs). Presented here is a summary of what we have found so far.
Since this work started before the final version of the catalog was ready, there might be some minor differences between what is reported here and what is actually in the DR4 catalog.
