Just datapointing about libraries ... the public library system would probably be able to supply copies of the books you require via interlibrary loan with a charge to you, but that would require much more in the way of resources when you take into account the packing and transport of the books from A to B (though most libraries I know DO re-use jiffy bags). It might be worth asking the questions to the university library in terms of disability access - can you get a borrower's pass because it would be seriously bad for you to have to sit in their environment to read? Also is there a way to pull strings as an "ex-alumni" or whatever it is of the insitution you originally studies at?
