We present the first results from our KODIAQ Z survey aimed at determining the metallicity distribution and physical properties of the z≳2 partial and full Lyman limit systems (pLLSs and LLSs; 16.2⩽logN{sub HI}<19), which are probed of the interface regions between the intergalactic medium (IGM) and galaxies. We study 31 H i-selected pLLSs and LLSs at 2.3
