We also visited the James Joyce statue which stands just off of O'Connell Street.  On O'Connell Street is the Parnell Monument.  Charles Stewart Parnell makes appearances in many of Joyce's works, most notably in a Christmas dinner scene in Chapter 1 of Portrait of the Artist as a Young Man and also in the story "Ivy Day in the Committee Room" in Dubliners.  Parnell was in fact a major political figure in Irish history, who brought upon his own downfall due to a love affair. 

Also on O'Connell Street is the Gresham Hotel which pops up in the story "The Dead," from Dubliners.  The characters in the story, Gabriel and Gretta Conroy, spend the night at the Gresham and Gretta recounts an old love from Galway who used to sing her a song called "Lass of Augrim."

There are actually many Joycean sites along O'Connell Street, including Clery's Department Store, the General Post Office (GPO) building, the O'Connell Bridge etc. 

More Joycean sites that we visited included the National Library of Ireland.  The library is Joycean is the setting for a chapter in Ulysses.  Also, it is a place where people studying Joyce would and can come for information verifying the places in his books.  It could have been a place for which he got some of his information as well. Dr. Wawrzycka explained that any factual information regarding Dublin during that time would be found in this library and she showed us shelves and shelves of "Thoms' Directory."  We were lucky enough to go upstairs and have a quick look around.  It is a very strict place, you can't even bring your backpack in or any pens!

We also stopped by the Dublin Writer's Museum.  We had lunch, browsed through the gift shop (which has tons of literary items of interest) and checked out the pictures on the walls.  There is also an exhibit on display.  The Writer's Museum is also a stop on the Dublin Bus Tour.  The exhibit part contains displays on Irish literature in past and present.  I highly recommend a visit. 

The Joycean sites in Dublin are innumerable.  Such places like Grafton Street, Nassau Street, the Liffey, Trinity College, Stephen's Green, I have not even mentioned.  The list goes on and on of places in his books as well as places he visited etc.  There are Joyce walking tours available, one is at the James Joyce Center.  You could actually just walk around town with any of his books, such as Dubliners, and stumble upon numerous sites from the book.  It's really an interesting way to explore the city.
