The LaTeX Package “marginnote”
In LaTeX the command \marginpar[⟨left⟩]{⟨right⟩} can be used to create
a note in the margin. But there is a problem with this command: It creates
a special kind of float. So it cannot be used on floats or footnotes. The
marginnote package supports another command \marginnote to create notes
in the margin. This does not use any kind of float and therefore does not
have the disadvantage of \marginpar. But there are other disadvantages,
which are either noted in the user manual or in the issue tracker.
The marginnote package originated from a question on the
TeX-D-L mailing list and a
few macros that I had created shortly before for a book project. The package
was marked as experimental from the start. A new maintainer is being sought,
so there is currently very limited to no support. An alternative would be, for
example, the package marginalia.
The package is hosted on Codeberg. Further information can be found in the CTAN catalog entry.
