You need to contact your academic liaison librarian Alan Bullimore
http://lrweb.beds.ac.uk/help/ALLs/Alan_Bullimore
and have a look at the on-line subject guide Alan has created for Law students:
http://lrweb.beds.ac.uk/law
If you can alert Alan to the titles you require he will get the loan status changed of the item you specify if possible - in other words if its a standard loan item (2 weeks) he will get it changed to 7 day loan item.
Alan will also contact the unit leader after speaking to you and we may be able to digitise a key chapter from certain texts to improve access.
Alan will also try to prioritise Public International Law texts when more funds become available
You could check the public library catalogue to see if a copy may be borrow from that source (you will need to join and get your own library card and PIN number to access it on-line): https://vpoint.culturalservices.net/bedford/
look for alternative titles at the same classification number
It is not unreasonable for you to consider buying a copy for yourself
