James Joyce's "Ulysses" alludes to hundreds of specific, mappable 1904-Dublin locations. Various Ulysses guidebooks have made preliminary attempts to pin these down and illustrate them.
Even lifelong Dublin residents will find many perplexing references, requiring research. The Internet is beginning to make such research much easier, but a new problem has arisen in that simple Google searches don't necessarily deliver the clearest or most reliable resources.
Google Maps now allows us to build innumerable free custom maps, using a powerful, evolving interface. (As a rule of thumb, it's easiest to add new locations by address-search, not copying from other maps.)
At its worst, this may confront us with a slow-loading, zoomed-out worldmap dotted with hundreds of anonymous-looking pins, or 'paddles'. Finding a particular location requires non-trivial skills in zooming, panning, and reading labels, followed then by doublechecking and 'antiquing' the modern map.
2008's Boston College Guide to Ulysses [gMap] has the most labeled locations, but it allows anyone to edit it so the reliability is uneven, and the hundreds of pins are slow and awkward to negotiate. There's a partial subset here.
Mulliken's 2010 project [gMap] is specific to Dubliners but more consistent and quicker.

Because GoogleMaps are free, you can break out subsets:
Ulysses episodes ['classic' version]
Calypso ['classic' gMaps version]
My new favorite nonGoogle map is this giant 1909 edition. The zooming function is buggy, and the cursor-key panning/scrolling doesn't update the url, so to create a link you have to trial-and-error unzoom-and-zoom until you land where you want.
Wandering Rocks is a special case
