National Library of Wales - the national storage for Welsh books (super digitisation now!), closed in the evenings, closed on Saturdays, closed also on Sundays and during snowfall!
Welsh-speakers are preferred here even though the head of this place comes from England, also: boring exhibitions and bad coffee!
Very good history here - and experts in their fields.
You cannot take your books home. Once staff "have their foot in there", they can rest, play
online games, dream, be depressed - and be off-sick as much as they like. A big
social club it seems to the
interested outsider. Just another institution.
