I'm an author and a coder, and I want to reference various parts of various notebooks in my latex project. I've tried doing the following, I'm looking for a better unified way of more tightly and elegantly coupling pieces of my mathematica work into my latex projects:

• Using hyperlinks to notebooks (too simple)
• Print the note as a pdf and embed it (printing in Mathematica is error prone)
• Manually export cells as images and include them as graphics (doesn't update when the code changes)

Yes, I realized this more of an open-ended discussion than a specific question.
