We created a sample of nearby QSOs selected from the Hamburg/ESO survey and the Veron-Cetty & Veron catalog, with a limiting redshift of z<0.06, which consists of 63 objects. In this contribution, we present the results of our ISAAC Ks-band spectroscopic and H and Ks-band photometric observations of 9 sources of this sample. In seven sources we find hydrogen recombination lines Paalpha and Brgamma of which five galaxies show a broad component. In three sources, extended molecular hydrogen emission is detected in the 1-0S(1) line. The stellar CO-absorption feature is only detectable in 5 objects, those sources with J-H and H-K colors closest to those of ordinary galaxies.
