The Canons of the Council in Trullo; Often Called The Quinisext Council 68Canon LXVIII.

It is unlawful for anyone to corrupt or cut up a book of the Old or New Testament or of our holy and approved preachers and teachers, or to give them up to the traders in books or to those who are called perfumers, or to hand it over for destruction to any other like persons: unless to be sure it has been rendered useless either by bookworms, or by water, or in some other way. He who henceforth shall be observed to do such a thing shall be cut off for one year. Likewise also he who buys such books (unless he keeps them for his own use, or gives them to another for his benefit to be preserved) and has attempted to corrupt them, let him be cut off.
