Portland, USA: You're not doing too badly when it comes to the Hal Spacejock books, are you? The distributor, ISBS, is based there. Powell's books of Portland stocks the entire series, and I've just had a NanoWrimo message from someone who works in the SF section at the Portland library telling me they have the books on their shelves.
I just took a peek in the Multnomah County Library online catalogue and they have 24 copies of various Hal Spacejock books across a number of branches.
So, if you live in the area and have been hanging out for some Hal, try the library ;-)
If you live elsewhere in the USA, you can either ask your local library to get them in (from ISBS), or move to Portland asap.
Surely that's not too much to ask?
