You and your students can make personal (not publicly viewable) annotations to embedded PDFs. The annotations live within the Library Course Reserve functionality, so they do not display if you download or print the file. 

1. Click the title of a document in a reading list.
2. In the right corner above the document, click for 'Full mode."
3. When you come to a place you want to annotate, select from the options along the top of the document window:
   • Highlight a selected section of text
   • Comment on a selected section of text
   • Draw a shape around a section of the document and add an optional comment
4. You can toggle between showing and hiding annotations.
5. Comments are searchable. Once you find a comment, click on it to go to where that comment is in the PDF.
