# Margin note on adjacent page

I was wondering if there was a way to put margin notes (and possible footnotes) on the adjacent page. I want to put together a document that incorporates a large amount of references and "margin definitions". Saving paper is not a concern for this particular document, and thought that it would be nice to do a one sided document for the body of the text, and have margin notes, footnotes and condensed citations on the opposite page.

Any help greatly appreciated...

• It would be better if you give more infos. Why distinguish footnote and marginpar, isn't really that you want a comments page? Sep 11 '15 at 8:03
• I want something similar to a comments page. The reason I don't consider it a comments page is that I generally consider a comments page as a construct used in the process of creating a document in a collaborative environment. You are correct that I did not have to distinguish between footnote and margin par. The reason I did however is that I generally think of a marginpar as little block of text that provides a definition or description that is used in the related text. whereas I generally think of a footnote as being something that points out some omitted detail, assumption, reference.

Update: No need to patch \@outputbox

Explanation Normal latex output routine calls commands \@makecol and \@opcol

command \@makecol normally saves the content of page (body text + footnotes) into vbox \@outputbox so we change it, now the body text is saved into \@outputbox and footnotes text into new box \mtbox.

command \@opcol call \@outputpage that shipout pages. We change it, now we call \@outputpage twice, first for the body text and then for the footnotes.

• The space for the footnotes is empty on the pages with text. Is it possible to change that? Oct 24 '19 at 6:30
• I will try to see. Sorry but i don't have time. Oct 28 '19 at 20:44
