Do you use a comma after a book title in a sentence?

Answer 1

I believe you do, if the sentence uses the word "book."

I was reading the book, The Monsters on Elm Street, (title would be underlined) when there came a knock on the door.

Answer 2

You should treat a book title like any other noun. Sometimes commas are needed, but often they aren't. it depends on the context. For example:

This semester we'll be reading TO KILL A MOCKINGBIRD in my English class.

No need for commas there. But in this example, commas are necessary:

The book I read last semester, TO KILL A MOCKINGBIRD, was written by Harper Lee.
