Getting the book list itself was pretty simple, really, even though the physical files were spread over several devices and/or formats.
In order to make my life easier, I decided that a ANSI/ASCII text file would present the fewest problems. The easy way to do this, of course, seemed to be to go into each device/format and email the files to one PC, and then "Save As..." to get them all to the same physical disk.
It was, suprisingly, just that simple.
