At present, we do not have the ability to increase access for individual users. The seat booking quota limit is there to ensure that everyone has equal access to a study space across the week. We are regularly reviewing the limit and will increase it as soon as we can. We are, however, experiencing a sharp increase in students with an urgent need to access the Library. Please check our website regularly for any updates to the seat booking system and other services - http://www.bris.ac.uk/library/.
We also suggest contacting your department to make them aware of your situation and see if they can offer some advice.
