Zusammenfassung:	A new multigroup cross-section library has been generated from ENDF/B-V data for use in defense-related radiation shielding applications. The library is available in a broad-group (46-neutron, 23-photon) energy structure and is designated DABL69. The establishment of specifications for the library, especially the specific group structure and energy weighting functions, was an important part of the generation of the library. The energy group structure contains some special tailoring to the oxygen and nitrogen cross sections and improved energy resolution in the range of 100-1000 keV where the iron cross section is highly structured. The library contains most materials of importance in defense-related shielding problems and includes several reference source spectra and response functions. The library is available in two formats including the commonly used ANISN format and the more versatile AMPX master format. Sponsored in part by the Defense Nuclear Agency.
