For a number of years I’ve had lofty goals to catalog my music library — not just the books, but also the individual pieces within the book, associated hymn tunes, composers, when I used a piece, etc. While I haven’t made much progress on the cataloging, awhile back I did create the underlying structure that would link everything back to Lutheran Service Book and the associated hymn tunes. Through that project I had the data to create several indexes that had more detail than those provided in the back of the LSB editions — primarily around the hymn tunes used in LSB.
