With regard to the works from January 1, 1928 to December 31, 1963, it is important to determine if the work is a multilayered work. That is, it contains more than one copyright. If so, you will need to gather facts about the status of each copyright contained within the work. A good place to start is by looking at the original copyright notice. Often other works might be listed.

The most common type of work to be multilayered is motion pictures. For this, we will use the American Christmas classic It’s a Wonderful Life, and examine how it fell into, and then (in essence), back out of the public domain.
