How to find the recording you're looking for: I think the best way to find a recording of a work is by bwv number, instrument, performer, or use search. The "by title" list is less useful because the work itself is not always included in the title of the recording. For example, Rosalyn Tureck Plays Bach contains a lot of different works, which you would not see listed in the titles index. Also, the Complete Works section of the site has a link if there is a recording listed for that particular work. Jan Hanford
