The book is a literal reprint of the 1966 edition. This includes the font in which that edition was printed. It would have helped if the publisher had recast the text in a more modern font, that current readers would find easier to read. Not that it's impossible with the original presentation, but there is a reason why fonts have changed in recent decades. Perhaps it would have added to the cost of this book to have done so.

Having said that, the text is a pleasure to read, at least for this reviewer, who studied complex analysis from Jerrold Marsden's "Basic Complex Analysis". The latter book is a more informal presentation than this. The current book emphasises the mathematical rigour, while Marsden focused on giving a pragmatic understanding of how to find contour integrals.

Compared to recent texts, Carrier's book is skimpy with diagrams. A more generous use of these would aid some readers new to the subject.
