I will review the literature on disks in binary systems in terms of the frequency of circumprimary, circumsecondary, and circumbinary disks as a function of separation of the stars. Great progress has been made in this field in the last few years with the advent of sensitive mid-infrared, submm, and mm observations at high spatial resolution that can pinpoint the source(s) of disk emission. Disks are found encircling stars spanning a wide range of stellar mass, whether in binary systems or not. By virtue of the need for spatial resolution, binary survey studies are more easily carried out in nearby star formation regions such as Taurus and Ophiuchus rather than in more distant massive OB associations such as Orion. Nevertheless, binary disk systems are known in Orion. Finally, I will discuss the later stages of disk/planet evolution with images of some well known spatially resolved debris disks that are in wide binary systems.
