Thanks for mentioning the credits page.

I see that David Christian has co-authored

Big History: Between Nothing and Everything (2013)
by David Christian, Cynthia Brown, and Craig Benjamin

which is 352 pages and costs about $70 on Amazon.

Since

Maps of Time: An Introduction to Big History (2011)
by David Christian

is 672 pages and costs only about $20, I may get this book instead.
