The 2010 PDR Electronic Library fully integrates on one CD all of these 4 books:
2010 PDR (everything the book has) +
2010 PDR Nonprescription Drugs/Dietary Supplements +
2010 PDR Ophthalmic Medicines +
2010 PDR Drug Interactions/Side Effects
This CD works on Windows XP, 2000, ME, 98SE but NOT on VISTA or MAC.
The PDR Electronic Library on CD has a 2-year life.
The software and data on the CD will expire on 6/30/12
Avoid the hardback "bookstore version" 2010 PDR book since it was published before the 2010 PDR on CD was available. So the 2010 PDR hardback book contains the 2009 CD. It expires 6 months before the 2010 PDR Elecronic Library CD here. Instead, get the more up-to-date actual 2010 PDR Electronic Library on CD here.
So, the 2010 PDR Electronic Library CD is much more up-to-date than the hardback 2010 PDR book's 2009 CD and much more comprehensive and much more convenient/portable than this heavy 10 lb book!
