Old documents

These are some old documents in PDF format that I have found while looking various things up.

American Shoemaking, 1915: A collection of editions of American Shoemaking magazine from the spring of 1915. Wonderful because it is so specific to shoemaking. (You will need to scroll down a few pages before you reach the content.)
The instruction manual for the Branston Violet Ray High Frequency Generator and Ozone and Sinusoidal Controller (fifth edition, 1920). Possibly not for the squeamish.
Detective magazine, Valentine's Day 1935: This is in French. My French isn't good enough to read more than bits of this, but I suspect that it isn't high-class literature.
New York Clipper, May 30, 1917: The New York Clipper was a weekly entertainment magazine that was published from 1853 to 1924, when it became part of Variety. This issue is a fascinating look at the world of old-time vaudeville.
Persons Sentenced To Death In Canada, 1867-1976: Lists those charged, along with a brief summary of their crimes, whether there was a recommendation for mercy, and whether execution was carried out.
