Rare original 19th c. set of the Annals of Ireland by the Four Masters, O'Donovan translation. In Irish and English, with instructions on how to break the set down into 7 volumes if desired. Matching set, each volume printed with the name of Rev. William Reeves, who served as president of the Royal Irish Academy in Dublin. http://www.irishroots.com/index.php/antiquarian-a-used-mainmenu-44
This page from O'Donovans Annals of the Kingdom of Ireland, gives directions on how to rebind the complete 5 book set into a 7 book set. It seems the five original books were rather large for some people.
