I have found a few authors writing in Esperanto. I'd like there to be more of that in the future. I have found quite a few things for free on the internet. Instead of that, I'd like to know that when I pay for something there'll be more literature in the future. Is there a publisher, for example, that someone could recommend?
There are a lot of bookshops and publishers from which you can order Esperanto books. Given that sending costs can depend on how far you live from the location of the bookshop of publisher, I will always mention which country they operate from.
The bookshop with the greatest choice of Esperanto books is certainly the Libroservo de UEA in the Netherlands. Furthermore, many national Esperanto associations have there own bookshops: The Esperanto-Retbutiko by the Flamish Esperanto League (FEL) in Belgium has a special position among them, as it serves customers from all over the world, functions as an important publisher and probably has the second biggest choice of books after the Libroservo de UEA. Other noteworthy examples are the Esperanto-USA Retbutiko (USA), Libroservo de GEA (Germany) and EAB Bookshop (UK).
You can also order books directly from the publishers. UEA and FEL are important publishers themselves. Here is a list of other important publishers:
- Mondial (USA)
- Sezonoj (Russia)
- Impeto (Russia)
- Espero (Slovakia)
- E@I (Slovakia)
- KAVA-PECH (Czechia)
- Edistudio (Italy)
If you want to follow what is happening in the Esperanto literature scene, you should subscribe to Beletra Almanako, a literary magazine published by Mondial (USA) that comes out three times a year in book format (you can also buy single issues).
Note that recently scams of Esperanto translations based on Google Translate (or some other not reliable machine translation) have appeared on Amazon. So don't buy an Esperanto book on Amazon without having seen that particular book or translation mentioned in a positive way on a serious Esperanto website.
Here's a link to the GEA's online bookstore.
