Contains most of the main (obvious) locations from Joyce's life and works, but the list is far from comprehensive and most of the fine detail is missing. For example, where is the 'smoothing iron' from An Encounter, and 25 Claude Rd, where J's father lived out the last 11 years of his life? A good 1st version, but it needs a lot more work to reach its full potential.

An unequivocal aspect to appreciating the works of Joyce. The best visual tour of Dublin city, flooded with extra information about all the locations. It really helps the works come alive. Top drawer.
