It's been a while since i had anything music related, so here's one from the Make blog for Tom:
This reminds me of a discussion that I had with Tom on pipe organ construction. Hey Tom, if you are reading this,
can you remind me of the title of the multi-volume Dover publication on pipe organ construction and theory that you have? can you verify that this is the book that you have that gives many details on pipe organ construction? I've been interested in picking up a copy, but never seem to remember the title.
