This is the kind of thing I find Archive.org and openlibrary invaluable for.
In this case a quick search didn't reveal it, but Google books has a scanned copy which you can use snippet view on so I wouldn't be surprised if there's a copy somewhere on archive.org
edit: hackernews regular gwern appears to have a digital copy of the book.
Considering that Walter appears to have not sold even the first printing of it (which is why copies of it are incredibly scarce - my guess is that most of it was pulped and only a few score copies ever sold, I still don't know how FH got one), I can assure you that you are not going to find anything better than my scan, and also that it's a lot better than nothing. (Someone needs to go through it & GEoD carefully, the influence is a lot greater than Dune critics previously realized.)
Oh yeah. I had to wait somewhere between 5 and 10 years before a copy finally surfaced online for <$120. I was terrified as I spent the $28 that the seller was going to realize what a huge pricing mistake they had made and would cancel my order (which happens occasionally), or that I'd get a different book (also happens occasionally...). Still, I scanned it myself just because getting another copy would be so hard.
