I actually don't think they went after Elder Scrolls at that time. According to the USEP article about it, they kind of just worshipped the Moths. If the name didn't already give that away. Since the scrolls have a connection to the moths they might've considered it sacred, but probably didn't go out hunting for all of them. Even if they wanted too, it would be pretty hard because it's not easy to travel around Tamriel when you grew up like nomads with few resources.
