This list is by no means exhaustive since it contains only a few of the more comprehensive and approachable volumes. Readers who wish to explore a wider range of the many books and articles devoted to Bach and his music should google Yo Tomita, Web sites with Bach Bibliography. Professor Tomita has amassed a comprehensive body of relevant material. There are articles on the individual cantatas in Wikipedia and the links at the bottom of this page are three of many available from which readers may access a range of Bach resources.
