Mika tells me that Greg Pomerantz — who still refuses to have his own blog — once bought a book called A History of Mathematics. He was looking for a book like it and this volume was sandwiched between several others sharing the similar name The History of Mathematics.
Greg went with A and he made the correct choice. It’s clear that the authors of the latter books got at least one thing wrong that the former got right.
I recently bought A Tour of the Calculus.
