  Binary stars have long been considered to play a crucial role in globular
cluster evolution, and offer the advantages of studying systems at the same,
well-determined distances. However, early search attempts were consistently
thwarted by crowding (particularly in the optical) and initial detections were
limited to small numbers of low-mass X-ray binaries (LMXBs) and a handful of
other systems. This resolution hurdle has been dramatically overcome by the
superb spatial resolution and sensitivity of HST and Chandra (supported by
advances in radio observations), enabling the detection in individual clusters
of more than 10, and in some cases more than 100, binaries. This review will
focus on detections of neutron star binaries, including recent optical
identifications, the exciting discoveries of multiple LMXBs in quiescence (with
the potential to constrain neutron star equations of state) and the detections
of millisecond pulsars (MSPs) in X-ray and optical images.
