<title>UK TeX FAQ -- question label marginparside</title>
</head><body>
<h3>Getting <code>\</code><code>marginpar</code> on the right side</h3>
<p/>In an ideal world, marginal notes would be in &ldquo;analogous&rdquo; places on
every page: notes on an even-side page would be in the left margin,
while those on an odd-side page would be in the right margin.  A
moment&rsquo;s thought shows that a marginal note on the left needs to be
typeset differently from a marginal note on the right.  The LaTeX
<code>\</code><code>marginpar</code> command therefore takes two arguments in a
<code>twoside</code> documents: 
<code>\</code><code>marginpar[</code><em>left text</em><code>]{</code><em>right text</em><code>}</code>.  LaTeX uses the
&ldquo;obvious&rdquo; test to
get the <code>\</code><code>marginpar</code>s in the correct margin, but a booby-trap arises
because TeX runs its page maker asynchronously.  If a
<code>\</code><code>marginpar</code> is processed while page n is being built, but
doesn&rsquo;t get used until page n+1, then the <code>\</code><code>marginpar</code> will turn
up on the wrong side of the page.  This is an instance of a general
problem: see

&ldquo;<a href="FAQ-oddpage.html">finding if you&rsquo;re on an odd or an even page</a>&rdquo;.
<p/>The solution to the problem is for LaTeX to &lsquo;remember&rsquo; which side
of the page each <code>\</code><code>marginpar</code> <em>should</em> be on.  The
<i>mparhack</i> package does this, using label-like marks stored in
the <code>.aux</code> file; the <i>memoir</i> class does likewise.
