These WD binaries with short orbital periods are important gravitational wave sources. However, the formation and evolution of WD binaries are not well understood. In this talk, I will discuss the formation of WD binaries with extremely low-mass WDs and AM CVn systems. In addition, I will discuss the soft X-ray emission of accreting WD binaries, their contribution to He II 4686 Å in elliptical galaxies and the properties of nova populations.
