For the catalog, we compiled the abundances of 28 chemical elements: alpha-elements (O, Mg, Si, Ca, Ti), carbon, iron-peak elements(Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn), slow and rapid neutron-capture elements (Sr, Y, Zr, Mo, Ba, La, Ce, Nd, Eu, Dy) and three odd-Z elements(Na, Al, K) in the stars of 69 globular clusters. The data are taken from 101 papers published from 1986 to 2018. The abundances of chemical elements in stars of the clusters in almost all the used papers are determined from high-resolution spectra obtained mainly for the atmospheres of red giants. The spectra are analyzed with the local thermodynamic equilibrium approximation.
