Hello
I used the search function, but didn't find an answer to my questions, so forgive me if I missed something ...
As far as I know, every ebook needs it's own identifier number (usually the ISBN Number), just like a paper book.
In epub the code looks like this
Code:
<dc:identifier id="PrimaryID" opf:scheme="ISBN"></dc:identifier>
My problem right now is: I just scanned an old book. I did all the ocr and stuff like that and now I start to turn the text into an epub file. But what about the ISBN Number? The book itself is from around 1886, and using ISBN just started about 90 years later. So what should I do now? Should I enter a fantasy number (and risking that another ebook also has the same number? Or should I leave it blank? Or is there a website where I can see what ISBN Number is available (and claim it - for free if possible, because I want to distribute it freely, here on MR)
