AIPS is a set of programs for the analysis of continuum and line VLBI observations involving one or more BB channel. These programs are available for a wide range of computer operating systems. Section 26.1 gives contact information. Extensive on-line internal documentation can be accessed within AIPS. An entire chapter in the AIPS Cookbook (NRAO staff, 1996) provides useful ``how-to'' guidance for those reducing VLBI data. A ``designated AIP'' program covers general AIPS user support, including VLBI. A designated AIP list is available on the WWW from the NRAO home page (see Section 26.3) and in the AIPS startup message at the AOC.
