We explain numerical methods to calculate low-lying eigenstates of the finite-size spin-1/2 anisotropic Heisenberg model. Sparse matrix techniques and a bit representation of spin configurations are shown to be quite useful in writing a program independent of specific lattice structure. A few examples of application are presented to demonstrate the effectiveness of our method.
