Yo Tomita, Research Fellow at Queens University, Belfast, UK, maintains this bibliography of over 14,000 items (scholarly books, articles, dissertations, and conference papers) on Johann Sebastian Bach. The somewhat cryptic interface allows for both simple and complex searches, with the complex search allowing users to specify type of music, general theme, language, and publication type. Users can consult a list of related journals and their abbreviations. Recent updates to the database, as well as new and forthcoming items, are also available.
