All files in this library are in Lilypond format. You can get Lilypond (with instructions) here. Most of the source code is ready for version 2.8.0; the version needed for each file is shown on the index pages.
I did not store finished output files for two reasons: first, they take up a lot of space; and second, having the input files makes it possible for you to make whatever changes you want (transposing, adding verses, changing words, using lilypond-book to create bulletins with music in them, or whatever).
To the best of my knowledge, everything here is in the public domain in the United States. If you're looking for a hymn written after 1923, that's why you can't find it. If you find something that is under copyright in the US, please let me know (contact info below) and I'll remove it.
This project grew out of my personal needs--in particular, the need to cut down on the number of books I carry when playing the organ, and to cut down on the amount of flipping through pages needed. I place the results in a three-ring binder (in sheet protectors) and place the music for any given liturgy in order. The point of all of this is that most of the hymns here are ones that I needed, along with some of my particular favorites. My primary source was The Hymnal 1940, with which I grew up. I have supplemented from a variety of other hymnals.
As noted above, the music and words are believed to be in the public domain. My source files are provided under Creative Commons Attribution-NonCommercial license 2.5 (see below).
