Have you ever received a query from Mongolia by someone who originally wrote their book in Mongolian, self-published that book in Mongolia but has now finished translating their book from Mongolian to English and would like to find an agent for their book in the English speaking market where it has not yet been published in any form?
OK, I don't speak Mongolian but I know you wanted blog posts that include Mongolia (now I've mentioned it enough, I think 😂).
Here's the reality and maybe it's a stupid thought/idea but sometimes I get stupid ideas: I wrote my first book in English and self-published it to KDP-Amazon UK and it is available in English, worldwide, and has been bought in at least eight different countries that I'm aware of. The ISBNs for all editions of this book (e-book, paperback, hardback) are mine - not Amazon's.
I am nearing the end of translating this book from English to German, and I am moving from the UK to Switzerland (German speaking part -> German speaking book market) next year. I had planned on just sticking the German edition onto Amazon as a self-published book as well, but then I had this thought: Would it be query-able for a German speaking agent? Like, what would YOU do if I queried you with an English edition of a book that was originally written in Mongolian and self-published in Mongolia?
The critical piece of info here is that you self-published it.
That means you didn't license the rights to publisher, you only offered the book for sale yourself.
If you had licensed the book to a publisher, an agent would need to see that contract to make sure you only licensed English language rights, not world rights.
If you license world rights, there's no deal to be made with you.
The deal would be with the publisher who now controls those rights.
So, you're free to query German language agents.
I have no idea how the domestic market works in Germany and Switzerland.
All that is handled by our co-agents who shop books there.
The ISBNs don't matter at all.
And most agents will want to take a look at the contract you signed with Amazon, just to make sure everything is hunky-dory.
