Calculating the Value of Library $ervice$

While reading the March 2010 issue of Library Journal I saw this device from the Swiss Army Librarian. Here is Brian Herzog's Library Value Calculator mentioned in that article. I thought it was an interesting gadget and tried adding it to the sidebar, but it's too large. Therefore, you must view it here, and through the links below this post. Click on the words "Value of Service" to see how he arrived at these values.
