There is a list of the Yamaha manuals Gary has somewhere; though I have never seen it myself. It was in notebook form, then was getting transferred to a disc, then disappeared... It was supposed to be making it's way to Terry at one point... I can't remember...we should have had that subject up again at the last meeting, when all the principals were present. If you really want to know, you'll have to call Gary.
In response to 'Borrow or Keep', it's sort of on the border between the two; there is no mechanism to recall the on-loan manuals, though there is a written record of what goes out, and it is being assumed the manual will be returned when the borrower's interest fades...
