We present an up-to-date catalog of pulsating binaries, i.e. the binary and multiple stellar systems containing pulsating components, along with a statistics on them. Compared to the earlier compilation by Soydugan et al.(2006a) of 25 δ Scuti-type `oscillating Algol-type eclipsing binaries' (oEA) plus 197 candidates,the recent collection of 74 oEA by Liakos et al.(2012), and the collection of Cepheids in binaries by Szabados (2003a), both the types of pulsating variables and binaries are now extended. The total numbers of pulsating binary/multiple stellar systems have increased to be 501 as of 2014 September 16, among which 262+ are oscillating eclipsing binaries and the oEA containing δ Scuti components are updated to be 93. The catalog is intended to be a collection of various pulsating binary stars across the Hertzsprung-Russell diagram. We reviewed the open questions, advances and prospects connecting pulsation/oscillation and binarity. The observational implication of binary systems with pulsating components, to stellar evolution theories is also addressed. In addition, a catalog consisting of 434 confirmed Algol-type eclipsing binaries (EA) is provided for reference.
