Joshua Rose, and "The Catechism of Steam", both in PDF. Excellent!

Michigan State University has been very helpful in hosting these images (it's been 4 years or so I think). If anyone out there has a similar book, a decent scanner, and inclination, I'd be happy to help with technical details, and if necessary the conversion to PDF. (Please ask--some details of the scanning process are not obvious, especially the format.) One of the books there was from a RCM reader that way.
Books need to be in the public domain (in the US, this means basically published before 1923--see ).

I almost forgot, "The Advanced Machinist" is also included. Those MSU boys are on the ball!

Yep! I found it when I visited the site from the original posting. I already had the others, but I downloaded this (thank goodness I now have a T1 line, instead of that 56k frame relay. :-)
I spent some time going through part of it, including the section on threading with a lathe. I find it interesting what was and was not available on lathes at that time (e.g. around 1902):
Not available:
+ Threading dial
+ Compound
+ Calibrated cross-feed dials
+ 3-jaw and 4-jaw chucks.
+ No sign of follower or steady rests.
Available:
+ Quick-change gearbox (on some)
+ Multi-point threading tool, lever indexed, to cut a thread in multiple passes without infeed on the cross-slide. Each pass was cut with a different point -- each one narrower and deeper than the previous.
Of course -- all threads were cut with direct infeed, since there was no compound to set at an angle.
But vertical boring mills were already available and in use.
And -- they described both how to cut threads with hand chasers (no leadscrew), and with a leadscrew, with the chasers sometimes being used to clean up a single-point cut thread.
And -- they gave details for cutting square (not Acme) threads to a stop drill.
I would probably still be reading it, if it did not take so long to step from page to page. :-)
An interesting discussion comparing the 60-degree threads with the Whitworth ones, pointing out the benefits and disadvantages of each.
Enjoy, DoN.

Don - Oh, shut up. I get a 26k connection on a good day.
Leon - Thanks for the link. What I've downloaded so far looks great.
