Using the Very Large Array (VLA), we have carried out a complete study of the HI absorption toward the central 250 pc of the Galactic Center (GC). The spatial resolution of 15" and velocity resolution of 2.5 km/s are a big improvement over the previous HI absorption study toward the central 50 pc of the GC by Lasenby et al. (1989). Here, we present (1) distance constraints to 40 well-known GC sources, (2) kinematics of the HI component toward many well-known GC sources, and (3) information on the line-of-sight arrangment of the ISM in the SgrA, SgrB and SgrC complexes. We have also created a website for the astronomical community which includes continuum images, HI absorption profiles, and HI data of all major regions of interest in the Galactic Center.
