Infinite Ulysses lets readers of James Joyce's challenging novel Ulysses (often named most important book of the twentieth century) while annotating it with their questions and interpretations and perusing annotations from fellow readers. The site also attempts to personalize the annotations displayed to each reader through a variety of mechanics such as filtering, sorting, and generating descriptive metadata around each annotation.

The site is built by Amanda Visconti on Drupal, Annotator.js, and improvements to the Annotator and Annotation Drupal modules authored by Michael Widner for Lacuna Stories. Technical innovations include my addition of social voting, favoriting, and moderation to annotations, and various experimental reading page designs.
