    "abstract": "The main formalisms of partial level densities (PLD) used in preequilibrium\nnuclear reaction models, based on the equidistant spacing model (ESM), are\nconsidered. A collection of FORTRAN77 functions for PLD calculation by using 14\nformalisms for the related partial-state densities is provided and 28 sample\ncases (73 versions) are described. The results are given in graphic form too.\nComposite (recommended) formulas, which include the optional use of various\ncorrections, i.e. the advanced pairing and shell correction in addition to the\nPauli effect, and average energy-dependent single-particle level densities for\nthe excited particles and holes, are also given. The formalism comprises the\ndensity of particle-hole bound states, and the effects of an exact correction\nfor the Pauli-exclusion principle are considered.
