I'm not sure such a thing would even be desirable. Even ignoring that there will be plenty of invalid data that you just have to find a way of dealing with, MARC is hopelessly complex and needs to be normalized before anything useful can be done with it. Unless the purpose of the validation is to determine if files supplied to you meet specifications (e.g. vendor provided files), I would imagine that validation would cause more problems than it would solve. kyle
