How can I reference a table/figure/section in another document?
I am writing a journal paper that has grown to 30 pages long, so I would like to split it into two 15 page parts: part I and part II. I plan to submit both parts to the same journal at the same time, so I would like to be able to reference figures/tables/sections from part I in the text of part II, and vice versa. However, I need a separate bibliography and a separate frontmatter (title, authors, abstract, etc.) for each part.
I'm aware of the multibib package, but I believe that only fixes the separate bibliography problem.
Any ideas on how to do this? Multiple part journal papers seem to be fairly common, so I would think someone would have found a solution to this.
