+<title>UK TeX FAQ -- question label eqnarray</title>
+</head><body>
+<h3>Why not use <code>eqnarray</code>?</h3>
+<p>The environment <code>eqnarray</code> is attractive for the
+occasional user of mathematics in LaTeX documents: it seems to
+allow aligned systems of equations. Indeed it <em>does</em> supply such
+things, but it makes a serious mess of spacing. In the system:
+<blockquote>
+<pre>
+\begin{eqnarray}
+ a & = & b + c \\
+ x & = & y - z
+\end{eqnarray}
+</pre>
+</blockquote>
+the spacing around the "=" signs is <em>not</em> that defined in the
+metrics for the font from which the glyph comes - it's
+<code>\</code><code>arraycolsep</code>, which may be set to some very odd value for reasons
+associated with real arrays elsewhere in the document.
+<p>The user is far better served by the AMSLaTeX bundle, which
+provides an <code>align</code> environment, which is designed with
+the needs of mathematicians in mind (as opposed to the convenience of
+LaTeX programmers). For this simple case (align is capable of far
+greater things), code as:
+<blockquote>
+<pre>
+\begin{align}
+ a & = b + c \\
+ x & = y - z
+\end{align}
+</pre>
+</blockquote>
