Not long ago, I asked my library to get
Pagan Christianity, not as a loaner but for in-stock. They got it, np. {I mainly ordered it for a pastor who was looking for it}.
One former {recently retired} librarian at my relatively small library is Presbyterian. He worked there for maybe 30 years and ordered all kinds of gr8! theology books from Westminster/Knox. However, the library was down-sizing for more shelf space and auctioned off many books I had assumed would always be there. I knew about the auction {books for like 50 cents!} but had to work that day and was too lazy to go afterward,
Among several books I totally missed out on getting for cheap! were:
The Christology of the New Testament, by Oscar Cullman (a classic}
The Method and Message of Jewish Apocalyptic, by D.S. Russell {awesome book!}
The Son of Man in Myth and History, by F.H. Borsch
HERMENEIA Commentaries! {the best around, retail for at least $75),
Thankfully, they didn't get rid of ALL the good books!
And, I must admit I don't especially care for many of the new books they're getting.
Maybe I should ask for some more?

{have not, ask not}....
Sue,
Won't Aussie libraries get you theology books if you ask them?
I mean, just to borrow for a couple weeks?
