I sent a text only file in MSWord format to Amazon last night for conversion and it worked much better than the pdf conversion except that all the hyperlinks that I put in so I could jump to individual songs did not work. Otherwise the result looks fine and there were page breaks in the right places.

I since found out that in converting from Open Office to Word, the internal hyperlinks got lost. I don't know if that's a bug in Open Office or not. I will have to look for the bug tracker - presumably in Libre Office now.

I have just sent another file to Amazon. This time I converted it to html (html is on the list of accepted file types for Amazon's converter) and the hyperlinks all saved OK. I had also converted all the inline music notation images into jpegs from Enhanced Metafile (the format my notation editor exports the music files as). I think that was partly the cause of the corrupted notation in the original pdf conversions I got back from Amazon. The Enhanced Metafile relies on a font provided by the notation editor to display or the music notation glyphs and the computer needs to have it installed for the notation to display correctly. I found that out when I went over to Linux. It was easily resolved in that case, I just had to make sure the necessary fonts were installed within Linux.

I'll report back when I pick up the html file from Amazon.
