"This collection of study materials covers every major topic of the internal medical clerkship, featuring select chapters and cases from across AccessMedicine's library." Basically, this feature provides a guided overview to a topic, and links to the appropriate content within the platform.
Each topic starts with learning objectives, then directs you to to ebook chapters, tables, charts, and case files for your own self study. Ignore the Export as.... option. This is only helpful if you want direct links to the content that works on campus. You will need to modify the URL's if you want them to work off campus. Ask a librarian if you do want to learn more.
