If I want to go into publishing/editing, what kind of masters degree should i get?

Unless you’re looking to become a newspaper editor, don’t worry about a masters’ degree right away: experience will count for a lot more early on in your career. (If you are planning to continue with the journalism track, you should focus on that.) If you really feel you need a credential, there are several editing and publishing certificate programs out there that might be worth investigating.

Journalism or English (Composition not literature)
