Hope this helps, Sharon The iBook Converter for PC is still available as of 2015. Here's an article with more details. In conclusion, I would say that the iBook Converter for PC works well. However, there are some things to watch out for: 1.) If you do not use a Mac, iBooks doesn't work. 2.) iBooks doesn't support exporting to PDF. You have to export to Apple-created .pub format. 3.) iBooks doesn't support all the formats that the iBook Converter for PC natively supports. 4.) It's a bit of a pain to have to go to Apple's website and download.
