Some have raised concern over whether Esperanto books sold on Amazon are legitimate or poor translations. E-USA sells authentic books through this Amazon link. Be on the lookout for a recommendation list from E-USA of other Esperanto books, not sold by us but still available on Amazon, that we have vetted and know to be authentic.
Remember when buying on Amazon to use the URL http://smile.amazon.com and select “Esperanto League of North America” as your designated charity. A small portion of each purchase you make through the Smile link will be donated to E-USA.
