Great Nations of Europe, 6 volumes, by Mary Platt Parmele (HC, 1907, $16 for the set of 6, which is less than 1/3 the price on the internet. )
The Short History of:
1. England, Ireland and Scotland
2. France
3. Germany
4. Italy
5. Spain
6. Russia
I am not sure if this is a complete set. It does occur to me that Ms. Parmele had to know an awful lot to be able write all these books. And it was a wonder she was even able to publish, as she was "only" a woman. Curious as ever, I checked her out on the internet, and found out her books are STILL IN PRINT! The Short History of Spain was, amazingly, just released in paperback less than a year ago! Parmele was originally from Albany. Her books were read in schools, but were written more for the general public.
Look for these books in the set section.
