Were you at the "books about books" panel in Dublin? The author of the "Library of the Unwritten" was there, that's where I heard about the book. Another panelist mentioned that many books written about "libraries" don't actually know what libraries are/are for and mix them up with e.g. archives, and several panelists definitely looked caught out ^^

I nominate to request. You might be right that it's not necessary to reread them before nominating; I'd just like to reread them before writing my requests.
