So the last few day's I've been trying to locate the Netziv's perush on the Sifrei, the Emek Hanetziv. It hasn't been easy. Google Search turned-up next-to nothing. Online bookstores don't have it. Most people I asked never heard of it. The two rabbis who I spoke who did know the book were divided as to whether it's just a standard perush included with the Sifrei or whether it's it's own book.
Well, a couple people told me to check out the library in the Central Ashkenazi Shul in Akko. I went to shacharit there(weekday davening is actually held in the library) and spent half the time peeking surreptitiously at the not-terribly-organized shelves. Then, suddenly I saw it. Three volumes of moderate width "Sifrei Emek Hanetziv".
It's a pity there's so little online about the book. These days, you can get all the basic Jewish texts online, at least as a scanned PDF, but there are still a lot of books with little or no mention online. I would love to scan the entire book and put it up, but I don't have the time or the equipment, so here at least are the pages I scanned for my own personal use, about Maakeh.
