Today I posted Advanced Practice in Gregg Shorthand, Parts 1, 2, and 3, on the Internet Archive.
These books are very rare. They include several readings for 1902 Pre-Anniversary Gregg Shorthand. They were published in 1913, 1914, and 1915. The English key for the Shorthand plates is found in Expert Speed Shorthand Course (1910, 1913), which is available on Google Books. The links for these items are included below:
