If these manuscripts contain falsehood or that their distribution contributes to falsehood, then it is not permissible to buy them, sell them, or keep them unless one wants to refute the falsehood that is in them. However, if they do not contain any falsehood or anything that supports falsehood, then there is no harm in buying them, selling them, or keeping them as there is no evidence which prohibits this as far as we know.
Allaah Knows best.
