Re: on a hard to find paper by Sobociński

[Richard Zach]

This is the Google Books link that worked for me:

https://books.google.ca/books?id=fNZLAAAAMAAJ&lpg=PA23&ots=Nw-L2XjS7I&pg=PA23

If you click on the cog icon in the top right corner it'll give you a 
link to download the volume as a PDF.

If that doesn't work for you and you don't want to go to the trouble of 
getting a VPN to fake a Canadian IP address, let me know.

(Canada, afaik, still has the 50 year limit on copyright as opposed to 
the 70 year limit that Disney has been trying to impose on the world.)
