Project Gutenberg has long had an interest in mathematics, perhaps because of its timelessness. This interest has been expressed in many ways, though perhaps some of them were misguided in retrospect. For example we published “texts” consisting of digits of π. To be fair, commercial publishers produced printed volumes of π! At that time, there wasn’t even a good way to represent the character for “π” on the internet!
