As fantastic as it is, the National Register of Historic Places can get a little confusing -- even for a seasoned pro. But fear not, because the PreservationNation blog has teamed up with Jim Gabbert, a historian with the National Park Service, to create our National Register Guide.

The former house of a celebrity would likely qualify for Criterion B of the National Register, but could also qualify for other criteria. Here, National Trust staffer Melissa Jest visits the John Coltrane House.

Episode Seven of our National Register of Historic Places Guide demonstrated how to establish a property's historic significance. Episode Eight identifies the different criteria and "areas of significance" that are important for National Register listing.

This episode answers specific questions such as:

• How many National Register criteria are there?
• What are the National Register criteria?
• How many criteria must a property qualify for to be listed on the National Register?
• How many areas of significance must a property qualify for to be listed on the National Register?
• Can a property qualify for multiple criteria?
• Can a property qualify for multiple areas of significance?

We hope you enjoy the show.
