Hi All. I think from the scanning discussions most of us use kurzweil which means all those ark files from openbook can't be validated. I think a good project for someone like Gisela or any other openbook users would be to convert .ark to .rtf so more books can be validated. I have an old version of open book v4.0 I think before switching to Kurzweil a few years ago. I can't convert .ark files from newer versions of openbook. In fact, the only reason I still have my old version is that I'm converting some personal and textbook files to .rtf. I also save kurzweil files as .rtf so I can refer to them within word when writing papers or reports for school and work. Just some thoughts.
