The maps included in this web site are from the book
 "A School Atlas of English History" 
ed. by Samuel Rawson Gardiner, M.A. LL.D. 
It was printed in London by:

Longmans, Green, and Co. in 1892. 

Well, since I finally redid this book for the Memorial Library, I decided to use 3 magnifying glasses and finish the index, hope it helps!
