If accessing books from overseas is a problem, there's all sorts of serviceable material available from before 1922 on Google Books. I know Zadkiel's edition of Lilly is there, and the 1806 two volume edition of Sibly's "Astrology," as are a number of books from Alan Leo. Sepharial's "Directional Astrology" is pretty complicated but seems clear and instructive.
I notice in The Mountain Astrologer that the "natal" chart for the founding of the United States is called the "Sibly" chart. Is that the same Sibly?
