1) My degree demands me to have around 50 lbs. of new books and reading each year. Second-hand books are not possible for my subject that changes every year.
2) The total cost of all this material is around $5000 USD.
3) I must have all this material with me while I travel repeatedly between North America and England during my degree, and I cannot afford exorbitant shipping or airline baggage fees each time.
I suffer from an eye condition that forbids reading on screen for long times. Thus buying the PDF versions for these books is not a possibility. What else can I do?
