Query: A better alternative

I am a clinical psychologist and need some drug info.The PDR is a perfect example of the difference between data and information and its publisher's high handedness is to be expected when it teams with M$.I just bought and love the Mosby 2004 Drug Guide. Better paper, easier to read, more usable info, and only $30. It is not completely 2004 (none are really current) and the index to brand names has a few omissions but these are minor problems.
