For Apt Studio and if:book I developed, designed and built The Golden Notebook online project.

A collaborative, online reading of the complete text of Nobel laureate Doris Lessing's classic novel, the site required a complete, accessible and useful reading application, and discussion systems for textual and general comments, and a lot of tinkering with open-source code. It worked, with some really interesting stuff going on around unique URLs, bookmarking, and physical/ebook interoperability.
