For the average birdwatcher visiting or working in Borneo, Phillipps Guide is much the best book to get. For the expert, Susan Myers Bird of Borneo(publ. New Holland) will be needed as well! This is because it is more detailed as an identification guide, with descriptions of juvenile and female plumages, and graphic analyses of songs. Myer’s is the favourite among professional bird guides, Phillipps amongst most of their customers.
