Basically, it's a form of written history.

However, the most common usage is a typo in the word anal which is probably why you're seeing this definition now.
I was looking at www.urbandictionary.com for information regarding anal but all I got was this bullshit.

Historical Record, has nothing to do with ANUS, and is not what Borat says on DA Ali G show, FO REAL.
Give me those annals so I can look at them.
