    "abstract": "In this paper a library for spin--angular integration in LS-coupling for\nmany-electron atoms is presented. The software is an implementation of a\nmethodology based on the second quantization in coupled tensorial form, the\nangular momentum theory in 3 spaces (orbital, spin and quasispin), and the\ngraphical technique of angular momentum. This implementation extends\napplications of the relevant methodology to open f- shells and leads to faster\nexecution of angular integration codes. The possibility of using some library\nroutines for solving various angular momentum problems in atomic physics is\nalso discussed.",
