The Rising Influence of Rising Affluence

[OakesCS]

the documents are all public but they've set up their websites so you can't back up thru the urls which might eventually get you to places where they don't want you. i suspect it's just a simple security protocol.

after i submitted the first post it occurred to me that HAL might have some other interesting things under the "...contents/Shale/..."
path so i googled the truncated path for all pdf documents and there ya go. Of course, you might find other wonderful things if you truncate before the 'Shale'. I frequently take this approach when i know there's likely to be something useful in a place but i don't know specific words or titles that may exist in a location.
