iBooks: Requested Resource Could Not Be Found

Is anybody familiar with this error?

Did you run your EPUB through epubcheck?

Yes, ePubCheck passes it, as do Calibre and Sigil's built-in checkers.

The advice given is very good advice. I don't get why you won't heed it?

I'm not going to heed it because it's irrelevant to my concerns! The book already works just fine outside of iBooks! Making changes to make it work better outside of iBooks wouldn't solve any of my problems!

Meanwhile, I was able to figure out a solution on my own — at least, I think this is the thing out of all the things I tried that worked.

I manually removed the UUID from the OPF and had Calibre generate a new one, then imported it into iTunes, which added an iTunes metadata .plist to the file. It now runs happily on all versions of Books.

What I offered is a 100% reliable workaround to the issue caused by how you are trying to do footnotes. While Apple is about 50% for phones in USA they are 12% to 15% elsewhere. Here the main iPad users are schools due to Apple incentives.

On eBooks, Amazon has 90% of the worldwide market and next highest dedicated ereaders all only fully support epub2, only various amounts of epub3.
Most ebooks are read on phone apps and Apple Books has maybe less than 8% of that world wide.

So
1) What you are trying to do isn't best for the Apple Ecosystem.
2) It limits you to maybe 8% or less of people that buy ebooks.

I'm only suggesting how footnotes are managed (i.e. activated), the actual formatting can be anything compatible. Also never use a link ONLY in the superscript number. Link the entire source word as we gave up the high resolution stylus when Resistive Touch PDAs died. Almost all modern touch is very low resolution. I actually use a slightly larger viewing font size if doing a lot of annotation as it makes selection very much easier.

You realize that you're beating your head against the wall, right?

Note that the OP's problem in this thread wasn't to do with the footnotes at all.

If the OP wants help with footnotes, I'm sure they'll ask in a new thread.

Paul:

Yes, as it turned OUT. I mean, we're good, but not prescient. :-)

P.S., plus, is there an actual forum or site rule that says, "thou shalt only answer what's asked?" "Thine opinions are unwelcome?"

I have no issue with suggestions made before footnotes were ruled out as the problem.

But members should not take over threads with their own personal hobby-horses.

What do you think of something like this for the footnote marker [01]? It's what I prefer in a normal font size.

Jon, did you read the message immediately prior to your message that I quoted?

Just had this problem. Scenario two here worked for me.
