  This is a survey on contact open books and contact Dehn surgery. The relation
between these two concepts is discussed, and various applications are sketched,
e.g. the monodromy of Stein fillable contact 3-manifolds, the Giroux-Goodman
proof of Harer's conjecture on fibred links, construction of symplectic caps to
fillings (Eliashberg, Etnyre), and detection of non-loose Legendrian knots with
the help of contact surgery.
