You buy it from here."
this is one of the few online ways you'll be able to buy the collection, but in addition, project pulp is a neat place, where you can find lots of strange and hard to get little publications of the speculative fiction genre. so even if you've no interest in this book, there are lots of other nifty things round there if you take the time and have a looksee.
