Title: Progress on LIGO - Laser Interferometer Gravitational-wave 
       Observatory

Abstract:  LIGO is a major initiative in physics and astrophysics
sponsored by the National Science Foundation to detect gravitational
waves from astrophysical sources. The talk will describe recent
progress in the laboratory research, the state of the design and
construction of the LIGO facilities, and review current work on
astrophysical sources.
