The subject line pretty much says it all: some marginal notes (beginning of the second page) do not appear on the correct side. (The question is: how can I fix this automatically?) Below is a MWE that I got from my code, where I removed as much text as possible (and replace the missing text by a vertical space). I tried to remove some equations and the itemize environment to simplify things further, but could not get the right value of \vspace to still illustrate the problem.


This is a partial answer to my problem ... If I write \strictpagecheck before each \marginpar and if I explictly write \marginparmargin{outer} (which is supposed to be the default), the notes on the second page all get positioned on the correct side. The problem is that the notes that were previously on the wrong side now partly overlap the other ones.


Commenting on an answer which was deleted by its author: I do not want the oneside option as this is going to be printed as a book. Also, I tried sidepar and it definitely does not work: the notes on the first page are on the wrong side and some of the ones on the second overlap. Eventually, I will want to add figures as well as text in the margins.

\documentclass[11pt,openany]{memoir}

\setstocksize{11in}{8.5in}
\settrimmedsize{\stockheight}{\stockwidth}{*}
\settypeblocksize{9.0in}{30pc}{*}
\setlrmargins{0.7in}{*}{*}
\setulmargins{1.0in}{*}{*}
\setheadfoot{30pt}{26pt}
\setheaderspaces{*}{30pt}{*}
\setmarginnotes{0.2in}{1.5in}{0.2in}
\checkandfixthelayout
%

\begin{document}
Some text to get things started.
\vspace*{17cm} % to minimize the amount of text on the page.

Some text\marginpar{First note} with some notes in the margin.
Some text\marginpar{Second note} with some notes in the margin.
Some text\marginpar{Third note} with some notes in the margin.

\begin{itemize}
\item First item.  
    $$A=B$$
\item Second item.
    $$A=B$$
\end{itemize}

Yet more text with a note\marginpar{Fourth note} followed by an equation.
$$
A = B
$$

Now we can see the problem.\marginpar{This note is on the wrong side.}. 
With some more text\marginpar{And another note on the wrong side.} 
so we can perhaps start seeing what is going on.
Some text added with other notes and a reasonably long sentence to keep
the notes somewhat separate\marginpar{Note 1 on the correct side}.
Some text added with other notes and a reasonably long sentence to keep 
the notes somewhat separate\marginpar{Note 2 also}.

\end{document}

one single \strictpagecheck in the preamble and it works fine for me. Remember that you will need several runs (the feature use labels to verify pages) –  daleif Mar 29 '12 at 20:47
    
No offence, but if you delete answers, then I don't think you will see particularly many people helping you. –  daleif Mar 29 '12 at 20:49
    
Hmm, I see the last problem. No idea what is going on here –  daleif Mar 29 '12 at 20:52
    
I've added it to my todo list, but I will not have time to work on it until easter. –  daleif Mar 29 '12 at 21:02
    
@daleif I have only deleted my own answer (which I can still see). Someone else posted a tentative answer and, when it did not solve the problem, asked that I document what I did before he deleted the answer. I would never delete an answer written by someone else - nor downvote it as I do appreciate the time that other people put into helping. –  André Mar 29 '12 at 21:07

The problem is intrinsic to LaTeX's marginpar implementation. One possible solution is as follows. This uses pdftex's \pdfsavepos extension, I think other newer engines have similar extensions. Also it would need to be packaged and made a bit more generic (and tested on more than this one input file). But basically the idea is that \marginpar just saves its text in a box (actually two boxes a left and right hand version) then on the next run, LaTeX uses information from \pdfsavepos to align the margin notes at the vertical position of the callout as saved in the aux file. If it would overlap a previous one it is moved down, the positioning is done with shrinkable glue so if the margin column gets too full, the glue will shrink (so notes will move up to allow later ones to fit).

So you're not using an insertion at all for this! Are there any drawbacks with respect to the original definition? –  Stephan Lehmke Apr 18 '12 at 16:27

This is an interesting problem, but turns out that is not isolated to memoir, memoir is just better at making it end in the right margin. See this example:

\documentclass[11pt]{article}
\usepackage{geometry}
\begin{document}
Some text to get hings started.
\vspace*{14.5cm} % to minimize the amount of text on the page.

\begin{itemize}
\item First item.  
    $$A=B$$
\item Second item.
    $$A=B$$
\end{itemize}

Yet more text with a note\marginpar{Fourth note} followed by an equation.
\[
A = B
\]

Now we can see the problem.AA\marginpar{This is the first note}. 
With some more textBB\marginpar{Second note} 
so we can perhaps start seeing what is going on.
Some text added with other notes and a reasonably long sentence to keep
the notes somewhat separateCC\marginpar{Third note}.
Some text added with other notes and a reasonably long sentence to keep 
the notes somewhat separateDD\marginpar{Forth note}.
\end{document}

I'll send this elsewhere

The overlapping problems are somewhat fixed by \usepackage{marginfix} but still the placement is strange. –  Stephan Lehmke Apr 11 '12 at 14:38
    
@daleif. Out of curiosity I substituted tufte-handout, tufte-book, and book for the article class in daleif's example. Nothing else was changed. The problem did not appear in the tufte classes, but did appear in the book class. –  zun Apr 11 '12 at 17:54

@zun: Maybe because tufte classes use mparhack? –  Joseph Apr 11 '12 at 20:16
