Quasi-holo-daguerrotyping
From Tardis Wiki, the free Doctor Who reference
Quasi-holo-daguerrotyping was a method of transcription. Demolition workers discovered a book in the basement of a Shoreditch secondary school in the 1990s, that among other forms of writing, utilised this format. The process was as yet unknown on Earth. (NOTVALID: The Susan Diaries)
