Well, that might be a bit of a problem. I've been recently trying to acquire the series myself (there's six in all) and am having a problem finding volumes three and five. Amazon.com can't seem to find #3. These are old novels that are considered science fiction classics. They were reprinted a few years back, but are now out of print again. I would say that your best bet is used book stores.
