Was This The World's Most Expensive Ebook?

Think $0.99 is too much to pay for some ebooks?  Try $7,681.26 (yes, that's the list price)
for a hardcover version of  Selected Nuclear Materials and Engineering Systems by
Materials Science International Team (MSIT).  According to The Digital Reader, this was
available as the most expensive Kindle ebook back in February (don't see the ebook version as of today's date) at $6431.20.

If the title doesn't grab you, consider the product description: "The present volume in the New Series of Landolt-Börnstein provides critically evaluated data on phase diagrams, crystallographic and thermodynamic data of ternary alloy systems."  I think that translates into I'm not the target audience.  Anyway, if you're looking to blow nearly two grand, here's the link: Amazon.com.  Amazon wants you to know that at its current price, you'll save $357.74.  What a deal!
