Most universities and colleges around the UK have stationary-shops either directly by their library or inside for students to purchase neccessary equipment.
Having a stationary shop with the essentials (notebooks, pencils, pens, highlighters etc) could prove to be helpful for those who have either left that equipment at their accommodation, or if student's find themselves with none left.
Currently, there is an area in the library by the vending machines that isn't utilised anymore as the mini 'cafe' is no longer situated there. I believe that by adding a small stationary shop, students as well as staff could benefit massively.
