No, humanengr.  Occasionally we get a request to produce a PDF version, but it is quite time-consuming to edit everything into 8-1/2 x 11 inch pages, and this task, which would also complicate our ongoing maintenance, has never made it off the bottom of the pile.  I don't think that we'll ever do it.

BookMacster's Help Book, like any Apple Help Book, is not supposed to be something that you'd read from cover to cover.  Ninety percent of it is technical details that are only interesting in special use cases, and would be extremely boring to anyone who just wants their bookmarks sorted and/or synced.  That's the idea.  Although we encourage new users to read the Getting Started page, to learn what BookMacster can do, I hope that few users would ever need to dig deeper than that.

Ooops. Found it!
