Hi Dan
I've got that book but unfortunately can't lend it to you as I'll be needed it myself as I'm in Bali the same week - sorry.
However, I ordered mine from Amazon.co.uk - it came promptly, in about 10 days, with an o/s delivery charge of about 10 english pounds. You may be lucky if you order quickly and get it delivered in time - though sometimes amazon do take longer than they advertise. Other nhbs.com may be able to deliver from the UK quickly.
Depending on where you're flying into in Bormeo, you may be able to get the book (or one of the simpler photographic guides) in an airport bookshop? When I was in Brunei, the tourist office did sell the photographic guides along with 'Birds of Borneo' and other natural history books for Borneo.
Sorry I can't be of more help, but it is hard to source field guides out here.
Good luck
Dave
