You can edit your records, including adding tags and notes after the record has been added to your list.
You can add notes to a record - eg. instructions for students to read a specific section only. Notes can be Public - seen by anyone who can access the list - or Private - seen only by you.
You can also add private notes in the same way, by clicking on Add Note under the Private Notes heading.
If you decide you no longer need a reading in your list, you can delete the reading.
You can also delete an entire section (week or module): this will delete all of the readings in that section.
