In this article, we review the recent experimental studies on the charmoniumlike states, mainly from the e(+)e(-) annihilation experiments BESIII, Belle, BaBar, and CLEO-c, and the hadron collider experiment LHCb. We discuss the results on the X(3872), the vector Y states [Y (4008), Y (4660), and those in e(+)e(-) -> pi(+)pi(-) h(c)], and the charged charmoniumlike Z(c)(-) states.
