A Sunday edition is a weekly newspaper published on Sundays. It carries the name of the paper that is available on weekdays. Usually, it is a specially expanded edition, often several times the thickness and weight of the weekday editions. There are generally special sections not found in the weekday editions, and the classified ads are usually greatly expanded in type and number. Hallmarks of many Sunday editions are:

• Color comics: In the past, weekday editions only carried black-and-white comics, and only the "Sunday funnies" were in color. Even today, the Sunday comics are more expanded versions of the weekday strips, with more panels and expanded plot lines. Some serial comics continue the same story line between the week and Sunday, while others have separate plot lines for the two.
• Sunday magazine: this is a special magazine only found in the Sunday paper. Some large papers produce their own, with the best known possibly being The New York Times Magazine, while other, smaller papers often buy a nationally-produced magazine.
• Advertising inserts: While special ad publications may be inserted during the week, they are usually larger and more numerous in the Sunday edition.
• Most Sunday editions have many pictures making them a lot easier to read
• Sunday editions are very important to newspaper collectors
