This is my first post and I'm new to Calibre conversion. I am trying to convert an epub that I designed to mobi. I need to change the ISBN number for the Kindle from the epub file. What I have done is copied the epub and changed the ISBN number in the content.opf and in the text of the Copyright page in preparation for the conversion to mobi. I made sure there were no other copies of the "old' epub in Calibre, added the edited epub (with the changed ISBN number) and converted to mobi.

Lo and behold, the mobi still has the original ISBN number in the copyright page even though I changed it! I double checked the epub that I added to make sure it was changed and it was.

Is there another place in Calibre where old copies of an epub are kept that it might be using for conversion? I'm beginning to think my eyes are playing a game with me.

Thanks!
