I seem to recall having read in some thread somewhere in the past -- but couldn't seem to find it again -- that there's a maximum file size for the individual HTML files within an ebook? I think it was something like 264kb or something around there.
Is that for real? In this Shakespeare book I'm working on, I have some files -- entire plays of his -- that are over 300kb (and one around 450kb) and in ADE on my PC, and in iBooks on my old iPad2, I don't seem to have any issues at all with them.
I should probably mention (as I have elsewhere, in other threads) that I had only intended to put this book up on the iTunes store -- pleeeeeeze don't shoot me!

-- but at the same time it would be nice if it worked all-around, of course, in case I do want to give it to someone for use on another device. I'm just not sure in what context file size would be an issue -- if, in fact, it is indeed an issue.
