# Include vs Input in my case

Suppose you have two fully finished thesis, with their own bibliography and their own appendices. When I include one into the other, there is (obviously) some interference between the two different bibliographies and two different appendices.

So my question is: what is the optimal solution so that I get only one bibliography and one appendix. Also, I would like the included file to consist of one large section with subsections and not as it is at the moment, which is: each sections of the included file gets a section of its own.
