info on Mary G. Kelty books

I’m looking at the series that Mary Gertrude Kelty wrote and was wondering if anyone had information on it.  I have the book The Beginnings of the American People and Nation, but there are others she wrote, too.  I’d like to know more about them before I just buy them.  The other titles are The Growth of the American People and Nation, and The Old World Beginnings of the American People and Nation.  There are also others, but I’m not sure of the titles.

Any help is appreciated!
