Excellent primer

REPOST FROM Amazon

It's really four-and-a-half stars. Since Teach Yourself Esperanto went out of print, this is almost certainly the best print-based Esp-o course for Anglophones.

My only gripes:
First, it needs an English-Esperanto glossary to complement its excellent Esperanto-English glossary.

Second, despite the third edition being published in 2004, this is book is essentially twenty-five years old. Its history of Esperanto has no information of anything happening since 1981 (despite the renaissance that the Internet has given the Esperanto movement), and the glossary has no computer/Web/electronic terms. The only difference I could discern between it and the second edition was a one-paragraph biographical note about the author.
