I have both so which would be the easiest? Perhaps you could list both processes. Thanks, Leni
I'm not familiar with Sigil but there is a tutorial You are not allowed to view links.
Using Calibre there are a couple of ways.
1. Convert book to rtf or html & do it manually.
2. Highlight the book, click convert, and use search and replace. This does not work if there are page numbers though and I haven't figured out a way to get it to remove all of them without listing each one.
My personal favorite is checking my library accounts to see if I can find a library ebook & borrow that.
