There are two ways to create a new list. You can either create a list from scratch, or you can copy an existing list which you can then edit.
Every new list has to be prefixed with either 'Subject to Approval' or 'Subject to Review. This means the list will be sent to the Academic Librarian, who will check the resources you have added for availability.
After the approval/review event the Library will save a copy of the list so that there is a record of the original list presented at the event. Once this has happened you can make changes to the List in RLO, should you want to, e.g. restructure the sections into themes or weeks, or add/remove resources.
