I am working on my doctoral project. I need to take a KJV Bible and edit it with some language specific corrections. I need to be able to for example take an older English word such as "thou" and change every instance of the word to "thou(ss)" where the (ss) is not in brackets, but rather the "ss" is a superscript. I need to be able to change all instances at the same time.

Typical Word Processing programs cannot do that, with the exception of WordPerfect by Corel, which I do not own and has other limitations.

What programs are out there that have such features? What programs are there which will also allow me to insert notations in a separate field under each verse, that will not upset primary text formatting.

I suppose one question I should ask is this: What do real bible publishers use to do their editing? Is there a simple program that just lets you do editing, or do I have to learn XML, or some other variation?

Thanks for the input.
