I actually don't think I was at that panel, although I'd have to go back through my Dublin recaps to be absolutely sure.

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

Hahahahaha! There are actually quite a few published authors who also work in libraries, although I don't think that libraries feature very heavily in their work.
