A reference tool designed for two distinct audiences: those who, having read Ulysses once, want to explore the complicated web of allusions that form a major element in the text; those more experienced Joyce scholars who wish to locate quickly all allusions to a particular element.   The Index is organized by page and line number from the 1961 Random House edi­tion of Ulysses. When readers find the name “Bob Doran” in that edition, for example, they can check the Index for all further ref­erences to Doran. Almost 100 pages later in Ulysses (167.29) Doran appears again. Here, as in all subsequent references to Doran, the In­dex refers readers back to 74.01.   Scholars tracing image patterns or check­ing the recurrence of certain elements for any reason will find this book immensely useful: through the alphabetical index at the end they will be able to locate easily any re­current element in which they have a partic­ular interest. No longer will they have to hunt through 800 pages to find each refer­ence to whatever interests them.   In working with the Index, scholars using British editions or the 1834 Random House Ulysses may want to consult a conversion table, such as those provided by Clive Hart or Leo Knuth in Topographical Guide to James Joyce’s “Ulysses” and The James Joyce Dictionary by Shari and Bernard Benstock.
