With this printing, something remarkable happens for More Effective C++: its thirtieth print run. So many printings is uncommon for any technical book, but it’s particularly surprising for this one, because our understanding of what it means to apply C++ effectively has undergone considerable change since the book’s initial publication in 1996. For me, that makes a thirtieth printing kind of a big deal. It’s also a somewhat ironic deal, because for many years More Effective C++ was a book I wasn’t especially fond of. Only its longevity has allowed me to develop an admiration and respect for it.
