You found his eBook under the My Digital Edition on the old device or on the website of the reseller how has buy the eBooks.
Not, the answer i was looking for at all! Do you realize how much work this would mean? First I would need to identify what books I had d/loaded to the earlier Digital Editions and I cannot do this from memory...next i would need to find the publisher .. no thanks, I'm done with e-pub
If you not save the eBooks on a hard disc you has no other change. I have only try to help if you not happy of the solution i can nothing do.
