Lore is a body of knowledge or tradition that is passed down among members of a culture, usually orally. It's the lore in "folklore," and responsible for spreading the word on mythical figures like Santa Claus, Paul Bunyan, and even Uncle Sam.
Most lore begins as an oral tradition, passed on by word of mouth, and only later takes on a written form. We tend to think of lore as something centuries-old, as in the British "Arthurian lore" surrounding the doings of the mythical King Arthur and his court. However, newer lore — such as baseball lore — is constantly springing up. Humans need and love their lore.
