Hi there,
If you still have your student card and university login, you should be able to access your uni's in-person and online resources, but it's always best to check with your uni's library services team. They will be able to help you more accurately- it may be that you have to fill in a form allowing you to use the resources, or you can just access them like normal.
I hope this helps- best of luck with your gap year!
