BANNED BOOKS ON GALLIFREY?

Of course, The Doctor is not supposed to cross his own timestream, so the Third Incarnation wouldn’t know that his future self, the Thirteenth Incarnation, would meet Mary Wollstonecraft Shelley on the night when she was inspired to write about the “modern Prometheus”.

It could be that the High Council of Time Lords banned the “Frankenstein” book from Gallifrey’s libraries and from the curriculum of their various levels of academia.  While they practiced regeneration, revitalizing themselves when they were “mostly dead”, they probably had serious qualms about bringing someone back from being completely dead.

By the way, the Lux Foundation Library planet had to have a copy “Frankenstein” in its massive data storage core, possibly more than one copy, as with any book, in a separate backup drive.
