To Kill a Mockingbird

A contributor has added a title page for the 1960 novel, with Harper Lee as the director, writer and producer. (The budget is completely fabricated.) I've seen this in the past with other classic novels where someone created a title page for a book. There's no "title delete" option, so I contacted the Help Desk and was told:

Our aim is to be the most complete and reliable source of movie, TV, and entertainment information on the web. In order to continue offering our users an accurate and trustworthy service, it is our policy not to alter or delete any kind of correct/factual information from our records.

Thank you for your understanding.

I understand that audiobooks are allowed as videos, but none of the information on the title page corresponds to that other than the attribute next to the novel's release date.

Is there some other reason that this novel has a title page?
