On my website Songbook (songbook1.wordpress.com):
All commentaries on the songs, sheet music, recordings etc. when not otherwise attributed are by Jim Radcliff, aka doc, the pilot of this contraption known as Songbook. I do all the research, collection, and organization of materials for the site. All of the pages and posts are created by and published by me. Excluding comments by visitors, which occasionally may include a video or helpful information that is incorporated into the site, I am the sole contributor to the site.
