Hi, I have a question about 'The Letters and Papers of the Reign of Henry VIII', 1910 (?). I've searched online, and am a bit confused as to what this is. While I know this, or at least part of this is available for view online/National Archives, I've seen references to it as a 21 volume set of books. Does anyone know if this exists? If so, is it basically a volume of copies of the primary sources, etc.? Also, is it available for purchase?
Thanks in advance!
