I am working on some unpublished texts that cover a period of over ten years and many thousands of pages. These texts need to be distilled into key ideas that ideally would be available as a kind of "top layer" document--with the original, more lengthy source document available as a "link" on another layer. Likewise the ability to have another layer of commentary would be very useful.
I am wondering if anyone can suggest software that can handle this. It is a non profit project so a team of volunteers would be using the software. I have been looking at the outlining feature in Ms Word and also Scrivener but wondering if there are any other suggestions.
Perhaps scholars who work on very long documents or translators may have some experience with this kind of challenge. Thanks!
