Kasparov on Modern Chess

The gremlins working at my website server host decided this would be a good time to take FTP out of service, so I'm temporarily blocked from making any updates to my site. Instead of continuing with my zonal page (last seen in Zonal Cycle 2004-2005), I have to punt. Looking at the ongoing list of possible topics (a long list), I see several reviews of Kasparov's series on Modern Chess, but no one source appears to have covered them all. While I'm not a big fan of Amazon customer reviews, they'll have to do.

Garry Kasparov on Modern Chess (Amazon.com):

• Part 1: Revolution in the 70's (March 2007) #150,712 in Books
  
• Part 2: Kasparov vs Karpov 1975-1985 (September 2008) #184,670
  
• Part 3: Kasparov v Karpov 1986-1987 (August 2009) #73,660
  
• Part 4: Kasparov v Karpov 1988-2009 (October 2010) #35,780

I started this topic in a previous post, Kasparov vs. Karpov 1975-1985, where I included the 'Sales Rank'. Although it's now called the 'Amazon Bestsellers Rank', I guess it's the same thing and have included the numbers for comparison. Revolution in the 70's has gone from #264,777 to #150,712. Way to go, Garry!
