Increased access to information is good for students and teachers, for "individual citizens diversifying their news sources," and for professionals exchanging research.
Step-by-step explanation:

Additionally, the phrase "individual citizens diversifying their news sources" is in quotes, indicating that it is a specific phrase that is being referred to. Therefore, we should include commas to set off this phrase as well.
