The monograph summarizes recent achievements in the calculation of matrix elements of local operators (form factors) for completely integrable models. In particular, it deals with sine-Gordon, chiral Gross-Neven and O(3) nonlinear s models. General requirements on form factors are formulated and explicit formulae for form factors of most fundamental local operators are presented for the above mentioned models.
