I don't know where else to ask this...

I subscribe to the MSDN Universal CDs

I'd like to dispose of the discs that have been superceded, but I still have lots of DVD's from the old numbering system.

The "Shipment Contents" web tool at msdn.microsoft.com shows a list of only 13 DVDs. Is it safe if I throw out everything except the 13 DVD's listed there?

TIA
