If ever a book needed a Kindle edition, this is it

From the review in American Scientist Online of Margaret A. Boden’s Mind as Machine: A History of Cognitive Science:

It is fortunate that Mind as Machine is highly readable, particularly because it contains 1,452 pages of text, divided into two very large volumes. Because the references and indices (which fill an additional 179 pages) are at the end of the second volume, readers will need to have it on hand as they make their way through the first. Given that together these tomes weigh more than 7 pounds, this is not light reading!

Pricing would be tricky, though. Amazon is asking $188, which is $62 off list price. What would be a reasonable charge for a volume (actually two!) which one could not lend out, or donate to a library…?
