I am currently working on a research proposal and have come across a problem: This research proposal builds on a previous research proposal of mine. I am a historian and it deals with the same topic but for a different time period.
Now, that means that I feel I have to cover some of the same literature and background information that I have also covered in the past proposal. Specifically, particularly the first few paragraphs cover similar literature and background information as the previous proposal. I do not take anything over verbatim of course, but in terms of who I cite and what I say in the beginning (where I also make clear that this project builds on the past project) is pretty similar in terms of structure and content to the last proposal.
Now, my question is whether this is generally fine or not? The thing is I do not really know how to do it differently unless I wish to intentionally worsen the proposal by leaving out major parts of background information and literature.
