Hi,

This might be of interest:
http://www.geartechnology.com/issues/

They just opened their archive for everyone.
I've been subscriber for a couple of years. Gearmag is a good resource
to find out what's brand-new, and what's the state of art in general.

There's a working search tool on catalogue page. Try eg. Planetary,
Turboprop, Helicopter, Nitriding, Superfinishing etc. - comes up great
stuff...

Cheers,
Petri
