Books can be attributed to "Anonymous" for several reasons:
* They are officially published under that name * They are traditional stories not attributed to a specific author * They are religious texts not generally attributed to a specific author
Books whose authorship is merely uncertain should be attributed to Unknown.
I enjoyed reading this. Something I've wanted to do for a long time. It took me longer than a year to complete it due to surgeries and pain medications. This past January, I started reading a day or more each morning when I got up. I recommend everyone to read it.
