The research of infall motion is a common means to study molecular cloud dynamics and the early process of star formation. Many works had been done in-depth research on infall. We searched the literature related to infall study of molecular cloud since 1994, summarized the infall sources identified by the authors. A total of 456 infall sources are cataloged. We classify them into high-mass and low-mass sources, in which the high-mass sources are divided into three evolutionary stages: prestellar, protostellar and HII region. We divide the sources into clumps and cores according to their sizes. The H_2_ column density values range from 1.21x10^21^ to 9.75x10^24^cm^-2^, with a median value of 4.17x10^22^cm^-2^. The H_2_ column densities of high-mass and low-mass sources are significantly separated. The median value of infall velocity for high-mass clumps is 1.12km/s, and the infall velocities of lowmass cores are virtually all less than 0.5km/s. There is no obvious difference between different stages of evolution. The mass infall rates of low-mass cores are between 10^-7^ and 10^-4^M_{sun}/yr, and those of high-mass clumps are between 10^-4^ and 10^-1^M{sun}_/yr with only one exception. We do not find that the mass infall rates vary with evolutionary stages.
