The problem with distance learning is that you are often miles away from any library and the books on the Bibliography are, in any case, on restricted loan. Before shrugging in despair, it is worth looking to see in the books you want are available online. I have found two sources particularly useful. The first is Google books who often have portions of books online. If you are doing the Isaiah module, have a look at The Church’s Bible: Isaiah.

The other source is Amazon who often have a “search inside” feature available. I think you will need an account to look at the books and it is worth trying both .co.uk or .com. To get an idea, try looking at Biblical Exegesis and the Formation of Christian Culture.
