I have an older book (it isn't copyrighted), and as a certain tribute and preservation, I'd like to transcribe this book to a digital form.
I was wondering what application to use to do this. I don't want to write it to a certain exact (paper) size, but rather something "variable", meaning that it can be either opened on a mobile device, or printed on any paper size.
I don't need any OCR apps. I will take time and care to transcribe it myself perfectly, I just don't know what application to use. Microsoft Word seems like an obvious answer, but it also seems like a lame one.
So, what would you recommend to achieve a professional, long-lasting result?
