I see. So it's a sort of a 1922/Gabler text....yet another version!!
I read Ulysses a few years ago and basically just plodded through it. I read the words on the page and I understood very little. I read it again this time last year with a little better grasp. More recently, I've been going through it page by page. I started in April and I am approaching the end of Lestrygonians.
I discovered Frank Delaney's Re:Joyce Podcast and it renewed my interest. So I started making my own notes in the margin using Gifford's annotations and Delaney's comments (up through Proteus anyway).
I am making my very own No Fear Ulysses. Any plans for Bloomsday?
