This question comes up a lot. There’s no need to overthink it. There are no wrong answers.
A straight list is fine. Adding a few reasons is very common. Longer annotations with just 2 or 3 items are fine too. Don’t bother with wiki-type summaries. Explaining why is always better than what. Don’t manufacture lists to project a certain image.
The required reading list helps put your school in context - English 12 is not the same everywhere, some read Finnegan’s Wake while others read To Kill A Mockingbird. The pleasure book list gives some insight into your interests - listing the Core books will not help. The print/electronic publications generally don’t need annotations and lets them know if/how you keep up with current events and your interests. And the other entertainment helps confirm other information about your social/economic/cultural background contained in your recommendations and essays.
