In this paper we present in detail Newton's method and its modification, based on the Continuous analog of Newton's method for computing periodic orbits of the planar three-body problem. The linear system at each step of the method is formed by solving a system of ODEs with the multiple precision Taylor series method. We consider zero angular momentum symmetric initial configuration with parallel velocities, bodies with equal masses and relatively short periods. Taking candidates for the correction method with greater return proximity as usual and correcting with the modified Newton's method, allows us to find some new topological families that are not included in the database in [SCIENCE CHINA Physics, Mechanics Astronomy 60.12 (2017)]
