I will attempt to maintain a list of sites from which you can download the book.  

I am reaching out to OER  (Open Educational Resources) sites to see if they will also host it.

You can always download the file from the links below.  Let me know if the links do not work.

The file is in Acrobat PDF format. It's size is about 38 MB and has about 866 pages.
