If you want to release your books as a publishing firm you can use your own ISBN. However, in this case we cannot list your books at the VLB for you – you will have to do this yourself.
However, the prerequisite is that you yourself have contracts with the book wholesalers.

If you apply for an ISBN, which isn’t connected with any fees, over us, we can list your book at the VLB for you. Having this in mind, if you use our ISBN it is mandatory to mention us as publishing firm in the copyright notice of your book.
