2009 PDR Electronic Library on CD will NOT be available until March 31, 2009. Amazon has misprinted the date available as December 31, 2008.
If you need an up-to-date version, get the November 2008 CD version available from a few sellers here on Amazon's 2008 PDR Electronic Library listing. Be sure the seller specifies that they are selling the November, 2008 version (3A version).
Physicians' Desk Reference PDR Electronic Library 2008
The PDR Electronic Library has the full PDR + 2008 PDR Nonprescription Drugs/Dietary Supplements + PDR Ophthalmic Medicines + PDR Drug Interactions/Side Effects all fully integrated on one CD.
The hardback "bookstore version" 2009 PDR book was published before the 2009 PDR on CD was available. So the 2009 PDR book contains the very old January 2008 CD.
So the PDR Electronic Library CD is always much more up-to-date than the hardback 2009 PDR book's 2008 CD and much more comprehensive and much more convenient/portable than this heavy 10 lb book! Many sellers on Amazon often sell it for less than $60.
