Nuclear　data　library　is　the　cornerstone　in　the　nuclear　reactor＇s　design　and　calculation.　The　WIMS-D　multi-group　library　and　ACE　format　library　(mainly　used　in　MCNP)　is　applied　frequently　in　the　nuclear　calculation.　We　have　developed　a　new　self-shielding　calculation　procedure　based　on　Wavelets　scaling　function　expansion　method.　This　procedure　needs　several　parts　in　both　WIMS-D　and　ACE　format　library.　So　the　consistency　of　two　libraries　becomes　a　very　serious　problem.　This　may　bring　in　large　errors.　In　this　paper,　NJOY　cross　section　processing　system　is　used　to　produce　new　WIMS-D　and　ACE　format　library　from　the　same　ENDF/B　data.　We　compute　some　homogenous　problems　using　new　and　old　libraries　in　WIMS-D　and　ACE　format.　The　results　of　the　two　new　libraries　and　the　old　libraries　are　compared　respectively　It　is　found　that　there　are　consistency　problems　between　the　two　libraries.　The　newly　produced　libraries　are　more　compatible　than　the　old　ones.
